            Determines what trace information appears on hover. If
            `none` or `skip` are set, no information is displayed
            upon hovering. But, if `none` is set, click and hover

        hovertemplate
            Template string used for rendering the information that
            appear on hover box. Note that this will override
            `hoverinfo`. Variables are inserted using %{variable},
            for example "y: %{y}" as well as %{xother}, {%_xother},
            {%_xother_}, {%xother_}. When showing info for several
            points, "xother" will be added to those with different
            x positions from the first point. An underscore before
            or after "(x|y)other" will add a space on that side,
            only when this field is shown. Numbers are formatted
            using d3-format's syntax %{variable:d3-format}, for
            example "Price: %{y:$.2f}".
            https://github.com/d3/d3-format/tree/v1.4.5#d3-format
            for details on the formatting syntax. Dates are
            formatted using d3-time-format's syntax
            %{variable|d3-time-format}, for example "Day:
            %{2019-01-01|%A}". https://github.com/d3/d3-time-
            format/tree/v2.2.3#locale_format for details on the
            date formatting syntax. Variables that can't be found
            will be replaced with the specifier. For example, a
            template of "data: %{x}, %{y}" will result in a value
            of "data: 1, %{y}" if x is 1 and y is missing.
            Variables with an undefined value will be replaced with
            the fallback value. The variables available in
            `hovertemplate` are the ones emitted as event data
            described at this link
            https://plotly.com/javascript/plotlyjs-events/#event-
            data. Additionally, all attributes that can be
            specified per-point (the ones that are `arrayOk: true`)
            are available. Finally, the template string has access
            to variables `value` and `label`. Anything contained in
            tag `<extra>` is displayed in the secondary box, for
            example `<extra>%{fullData.name}</extra>`. To hide the
            secondary box completely, use an empty tag
            `<extra></extra>`.
        hovertemplatefallback
            Fallback string that's displayed when a variable
            referenced in a template is missing. If the boolean
            value 'false' is passed in, the specifier with the
            missing variable will be displayed.
        hovertext
            Sets hover text elements associated with each (x,y)
            pair. If a single string, the same string appears over
            all the data points. If an array of string, the items
            are mapped in order to the this trace's (x,y)
            coordinates. To be seen, trace `hoverinfo` must contain
            a "text" flag.
        ids
            Assigns id labels to each datum. These ids for object
            constancy of data points during animation. Should be an
            array of strings, not numbers or any other type.
        insidetextanchor
            Determines if texts are kept at center or start/end
            points in `textposition` "inside" mode.
        insidetextfont
            Sets the font used for `text` lying inside the bar.
        legend
            Sets the reference to a legend to show this trace in.
            References to these legends are "legend", "legend2",
            "legend3", etc. Settings for these legends are set in
            the layout, under `layout.legend`, `layout.legend2`,
            etc.
        legendgroup
            Sets the legend group for this trace. Traces and shapes
            part of the same legend group hide/show at the same
            time when toggling legend items.
        legendgrouptitle
            :class:`plotly.graph_objects.bar.Legendgrouptitle`
            instance or dict with compatible properties
        legendrank
            Sets the legend rank for this trace. Items and groups
            with smaller ranks are presented on top/left side while
            with "reversed" `legend.traceorder` they are on
            bottom/right side. The default legendrank is 1000, so
            that you can use ranks less than 1000 to place certain
            items before all unranked items, and ranks greater than
            1000 to go after all unranked items. When having
            unranked or equal rank items shapes would be displayed
            after traces i.e. according to their order in data and
            layout.
        legendwidth
            Sets the width (in px or fraction) of the legend for
            this trace.
        marker
            :class:`plotly.graph_objects.bar.Marker` instance or
            dict with compatible properties
        meta
            Assigns extra meta information associated with this
            trace that can be used in various text attributes.
            Attributes such as trace `name`, graph, axis and
            colorbar `title.text`, annotation `text`
            `rangeselector`, `updatemenues` and `sliders` `label`
            text all support `meta`. To access the trace `meta`
            values in an attribute in the same trace, simply use
            `%{meta[i]}` where `i` is the index or key of the
            `meta` item in question. To access trace `meta` in
            layout attributes, use `%{data[n[.meta[i]}` where `i`
            is the index or key of the `meta` and `n` is the trace
            index.
        name
            Sets the trace name. The trace name appears as the
            legend item and on hover.
        offset
            Shifts the position where the bar is drawn (in position
            axis units). In "group" barmode, traces that set
            "offset" will be excluded and drawn in "overlay" mode
            instead.
        offsetgroup
            Set several traces linked to the same position axis or
            matching axes to the same offsetgroup where bars of the
            same position coordinate will line up.
        opacity
            Sets the opacity of the trace.
        orientation
            Sets the orientation of the bars. With "v" ("h"), the
            value of the each bar spans along the vertical
            (horizontal).
        outsidetextfont
            Sets the font used for `text` lying outside the bar.
        selected
            :class:`plotly.graph_objects.bar.Selected` instance or
            dict with compatible properties
        selectedpoints
            Array containing integer indices of selected points.
            Has an effect only for traces that support selections.
            Note that an empty array means an empty selection where
            the `unselected` are turned on for all points, whereas,
            any other non-array values means no selection all where
            the `selected` and `unselected` styles have no effect.
        showlegend
            Determines whether or not an item corresponding to this
            trace is shown in the legend.
        text
            Sets text elements associated with each (x,y) pair. If
            a single string, the same string appears over all the
            data points. If an array of string, the items are
            mapped in order to the this trace's (x,y) coordinates.
            If trace `hoverinfo` contains a "text" flag and
            "hovertext" is not set, these elements will be seen in
            the hover labels.
        textangle
            Sets the angle of the tick labels with respect to the
            bar. For example, a `tickangle` of -90 draws the tick
            labels vertically. With "auto" the texts may
            automatically be rotated to fit with the maximum size
            in bars.
        textfont
            Sets the font used for `text`.
        textposition
            Specifies the location of the `text`. "inside"
            positions `text` inside, next to the bar end (rotated
            and scaled if needed). "outside" positions `text`
            outside, next to the bar end (scaled if needed), unless
            there is another bar stacked on this one, then the text
            gets pushed inside. "auto" tries to position `text`
            inside the bar, but if the bar is too small and no bar
            is stacked on this one the text is moved outside. If
            "none", no text appears.
        texttemplate
            Template string used for rendering the information text
            that appears on points. Note that this will override
            `textinfo`. Variables are inserted using %{variable},
            for example "y: %{y}". Numbers are formatted using
            d3-format's syntax %{variable:d3-format}, for example
            "Price: %{y:$.2f}".
            https://github.com/d3/d3-format/tree/v1.4.5#d3-format
            for details on the formatting syntax. Dates are
            formatted using d3-time-format's syntax
            %{variable|d3-time-format}, for example "Day:
            %{2019-01-01|%A}". https://github.com/d3/d3-time-
            format/tree/v2.2.3#locale_format for details on the
            date formatting syntax. Variables that can't be found
            will be replaced with the specifier. For example, a
            template of "data: %{x}, %{y}" will result in a value
            of "data: 1, %{y}" if x is 1 and y is missing.
            Variables with an undefined value will be replaced with
            the fallback value. All attributes that can be
            specified per-point (the ones that are `arrayOk: true`)
            are available. Finally, the template string has access
            to variables `value` and `label`.
        texttemplatefallback
            Fallback string that's displayed when a variable
            referenced in a template is missing. If the boolean
            value 'false' is passed in, the specifier with the
            missing variable will be displayed.
        uid
            Assign an id to this trace, Use this to provide object
            constancy between traces during animations and
            transitions.
        uirevision
            Controls persistence of some user-driven changes to the
            trace: `constraintrange` in `parcoords` traces, as well
            as some `editable: true` modifications such as `name`
            and `colorbar.title`. Defaults to `layout.uirevision`.
            Note that other user-driven trace attribute changes are
            controlled by `layout` attributes: `trace.visible` is
            controlled by `layout.legend.uirevision`,
            `selectedpoints` is controlled by
            `layout.selectionrevision`, and `colorbar.(x|y)`
            (accessible with `config: {editable: true}`) is
            controlled by `layout.editrevision`. Trace changes are
            tracked by `uid`, which only falls back on trace index
            if no `uid` is provided. So if your app can add/remove
            traces before the end of the `data` array, such that
            the same trace has a different index, you can still
            preserve user-driven changes if you give each trace a
            `uid` that stays with it as it moves.
        unselected
            :class:`plotly.graph_objects.bar.Unselected` instance
            or dict with compatible properties
        visible
            Determines whether or not this trace is visible. If
            "legendonly", the trace is not drawn, but can appear as
            a legend item (provided that the legend itself is
            visible).
        width
            Sets the bar width (in position axis units).
        x
            Sets the x coordinates.
        x0
            Alternate to `x`. Builds a linear space of x
            coordinates. Use with `dx` where `x0` is the starting
            coordinate and `dx` the step.
        xaxis
            Sets a reference between this trace's x coordinates and
            a 2D cartesian x axis. If "x" (the default value), the
            x coordinates refer to `layout.xaxis`. If "x2", the x
            coordinates refer to `layout.xaxis2`, and so on.
        xcalendar
            Sets the calendar system to use with `x` date data.
        xhoverformat
            Sets the hover text formatting rule for `x` using d3
            formatting mini-languages which are very similar to
            those in Python. For numbers, see:
            https://github.com/d3/d3-format/tree/v1.4.5#d3-format.
            And for dates see: https://github.com/d3/d3-time-
            format/tree/v2.2.3#locale_format. We add two items to
            d3's date formatter: "%h" for half of the year as a
            decimal number as well as "%{n}f" for fractional
            seconds with n digits. For example, *2016-10-13
            09:15:23.456* with tickformat "%H~%M~%S.%2f" would
            display *09~15~23.46*By default the values are
            formatted using `xaxis.hoverformat`.
        xperiod
            Only relevant when the axis `type` is "date". Sets the
            period positioning in milliseconds or "M<n>" on the x
            axis. Special values in the form of "M<n>" could be
            used to declare the number of months. In this case `n`
            must be a positive integer.
        xperiod0
            Only relevant when the axis `type` is "date". Sets the
            base for period positioning in milliseconds or date
            string on the x0 axis. When `x0period` is round number
            of weeks, the `x0period0` by default would be on a
            Sunday i.e. 2000-01-02, otherwise it would be at
            2000-01-01.
        xperiodalignment
            Only relevant when the axis `type` is "date". Sets the
            alignment of data points on the x axis.
        y
            Sets the y coordinates.
        y0
            Alternate to `y`. Builds a linear space of y
            coordinates. Use with `dy` where `y0` is the starting
            coordinate and `dy` the step.
        yaxis
            Sets a reference between this trace's y coordinates and
            a 2D cartesian y axis. If "y" (the default value), the
            y coordinates refer to `layout.yaxis`. If "y2", the y
            coordinates refer to `layout.yaxis2`, and so on.
        ycalendar
            Sets the calendar system to use with `y` date data.
        yhoverformat
            Sets the hover text formatting rule for `y` using d3
            formatting mini-languages which are very similar to
            those in Python. For numbers, see:
            https://github.com/d3/d3-format/tree/v1.4.5#d3-format.
            And for dates see: https://github.com/d3/d3-time-
            format/tree/v2.2.3#locale_format. We add two items to
            d3's date formatter: "%h" for half of the year as a
            decimal number as well as "%{n}f" for fractional
            seconds with n digits. For example, *2016-10-13
            09:15:23.456* with tickformat "%H~%M~%S.%2f" would
            display *09~15~23.46*By default the values are
            formatted using `yaxis.hoverformat`.
        yperiod
            Only relevant when the axis `type` is "date". Sets the
            period positioning in milliseconds or "M<n>" on the y
            axis. Special values in the form of "M<n>" could be
            used to declare the number of months. In this case `n`
            must be a positive integer.
        yperiod0
            Only relevant when the axis `type` is "date". Sets the
            base for period positioning in milliseconds or date
            string on the y0 axis. When `y0period` is round number
            of weeks, the `y0period0` by default would be on a
            Sunday i.e. 2000-01-02, otherwise it would be at
            2000-01-01.
        yperiodalignment
            Only relevant when the axis `type` is "date". Sets the
            alignment of data points on the y axis.
        zorder
            Sets the layer on which this trace is displayed,
            relative to other SVG traces on the same subplot. SVG
            traces with higher `zorder` appear in front of those
            with lower `zorder`.

        Construct a new Bar object

        The data visualized by the span of the bars is set in `y` if
        `orientation` is set to "v" (the default) and the labels are
        set in `x`. By setting `orientation` to "h", the roles are
        interchanged.

        Parameters
        ----------
        arg
            dict of properties compatible with this constructor or
            an instance of :class:`plotly.graph_objs.Bar`
        alignmentgroup
            Set several traces linked to the same position axis or
            matching axes to the same alignmentgroup. This controls
            whether bars compute their positional range dependently
            or independently.
        base
            Sets where the bar base is drawn (in position axis
            units). In "stack" or "relative" barmode, traces that
            set "base" will be excluded and drawn in "overlay" mode
            instead.
        cliponaxis
            Determines whether the text nodes are clipped about the
            subplot axes. To show the text nodes above axis lines
            and tick labels, make sure to set `xaxis.layer` and
            `yaxis.layer` to *below traces*.
        constraintext
            Constrain the size of text inside or outside a bar to
            be no larger than the bar itself.
        customdata
            Assigns extra data each datum. This may be useful when
            listening to hover, click and selection events. Note
            that, "scatter" traces also appends customdata items in
            the markers DOM elements
        dx
            Sets the x coordinate step. See `x0` for more info.
        dy
            Sets the y coordinate step. See `y0` for more info.
        error_x
            :class:`plotly.graph_objects.bar.ErrorX` instance or
            dict with compatible properties
        error_y
            :class:`plotly.graph_objects.bar.ErrorY` instance or
            dict with compatible properties
        hoverinfo
            Determines what trace information appears on hover. If
            `none` or `skip` are set, no information is displayed
            upon hovering. But, if `none` is set, click and hover
            events are still fired.
        hoverlabel
            :class:`plotly.graph_objects.bar.Hoverlabel` instance
            or dict with compatible properties
        hovertemplate
            Template string used for rendering the information that
            appear on hover box. Note that this will override
            `hoverinfo`. Variables are inserted using %{variable},
            for example "y: %{y}" as well as %{xother}, {%_xother},
            {%_xother_}, {%xother_}. When showing info for several
            points, "xother" will be added to those with different
            x positions from the first point. An underscore before
            or after "(x|y)other" will add a space on that side,
            only when this field is shown. Numbers are formatted
            using d3-format's syntax %{variable:d3-format}, for
            example "Price: %{y:$.2f}".
            https://github.com/d3/d3-format/tree/v1.4.5#d3-format
            for details on the formatting syntax. Dates are
            formatted using d3-time-format's syntax
            %{variable|d3-time-format}, for example "Day:
            %{2019-01-01|%A}". https://github.com/d3/d3-time-
            format/tree/v2.2.3#locale_format for details on the
            date formatting syntax. Variables that can't be found
            will be replaced with the specifier. For example, a
            template of "data: %{x}, %{y}" will result in a value
            of "data: 1, %{y}" if x is 1 and y is missing.
            Variables with an undefined value will be replaced with
            the fallback value. The variables available in
            `hovertemplate` are the ones emitted as event data
            described at this link
            https://plotly.com/javascript/plotlyjs-events/#event-
            data. Additionally, all attributes that can be
            specified per-point (the ones that are `arrayOk: true`)
            are available. Finally, the template string has access
            to variables `value` and `label`. Anything contained in
            tag `<extra>` is displayed in the secondary box, for
            example `<extra>%{fullData.name}</extra>`. To hide the
            secondary box completely, use an empty tag
            `<extra></extra>`.
        hovertemplatefallback
            Fallback string that's displayed when a variable
            referenced in a template is missing. If the boolean
            value 'false' is passed in, the specifier with the
            missing variable will be displayed.
        hovertext
            Sets hover text elements associated with each (x,y)
            pair. If a single string, the same string appears over
            all the data points. If an array of string, the items
            are mapped in order to the this trace's (x,y)
            coordinates. To be seen, trace `hoverinfo` must contain
            a "text" flag.
        ids
            Assigns id labels to each datum. These ids for object
            constancy of data points during animation. Should be an
            array of strings, not numbers or any other type.
        insidetextanchor
            Determines if texts are kept at center or start/end
            points in `textposition` "inside" mode.
        insidetextfont
            Sets the font used for `text` lying inside the bar.
        legend
            Sets the reference to a legend to show this trace in.
            References to these legends are "legend", "legend2",
            "legend3", etc. Settings for these legends are set in
            the layout, under `layout.legend`, `layout.legend2`,
            etc.
        legendgroup
            Sets the legend group for this trace. Traces and shapes
            part of the same legend group hide/show at the same
            time when toggling legend items.
        legendgrouptitle
            :class:`plotly.graph_objects.bar.Legendgrouptitle`
            instance or dict with compatible properties
        legendrank
            Sets the legend rank for this trace. Items and groups
            with smaller ranks are presented on top/left side while
            with "reversed" `legend.traceorder` they are on
            bottom/right side. The default legendrank is 1000, so
            that you can use ranks less than 1000 to place certain
            items before all unranked items, and ranks greater than
            1000 to go after all unranked items. When having
            unranked or equal rank items shapes would be displayed
            after traces i.e. according to their order in data and
            layout.
        legendwidth
            Sets the width (in px or fraction) of the legend for
            this trace.
        marker
            :class:`plotly.graph_objects.bar.Marker` instance or
            dict with compatible properties
        meta
            Assigns extra meta information associated with this
            trace that can be used in various text attributes.
            Attributes such as trace `name`, graph, axis and
            colorbar `title.text`, annotation `text`
            `rangeselector`, `updatemenues` and `sliders` `label`
            text all support `meta`. To access the trace `meta`
            values in an attribute in the same trace, simply use
            `%{meta[i]}` where `i` is the index or key of the
            `meta` item in question. To access trace `meta` in
            layout attributes, use `%{data[n[.meta[i]}` where `i`
            is the index or key of the `meta` and `n` is the trace
            index.
        name
            Sets the trace name. The trace name appears as the
            legend item and on hover.
        offset
            Shifts the position where the bar is drawn (in position
            axis units). In "group" barmode, traces that set
            "offset" will be excluded and drawn in "overlay" mode
            instead.
        offsetgroup
            Set several traces linked to the same position axis or
            matching axes to the same offsetgroup where bars of the
            same position coordinate will line up.
        opacity
            Sets the opacity of the trace.
        orientation
            Sets the orientation of the bars. With "v" ("h"), the
            value of the each bar spans along the vertical
            (horizontal).
        outsidetextfont
            Sets the font used for `text` lying outside the bar.
        selected
            :class:`plotly.graph_objects.bar.Selected` instance or
            dict with compatible properties
        selectedpoints
            Array containing integer indices of selected points.
            Has an effect only for traces that support selections.
            Note that an empty array means an empty selection where
            the `unselected` are turned on for all points, whereas,
            any other non-array values means no selection all where
            the `selected` and `unselected` styles have no effect.
        showlegend
            Determines whether or not an item corresponding to this
            trace is shown in the legend.
        text
            Sets text elements associated with each (x,y) pair. If
            a single string, the same string appears over all the
            data points. If an array of string, the items are
            mapped in order to the this trace's (x,y) coordinates.
            If trace `hoverinfo` contains a "text" flag and
            "hovertext" is not set, these elements will be seen in
            the hover labels.
        textangle
            Sets the angle of the tick labels with respect to the
            bar. For example, a `tickangle` of -90 draws the tick
            labels vertically. With "auto" the texts may
            automatically be rotated to fit with the maximum size
            in bars.
        textfont
            Sets the font used for `text`.
        textposition
            Specifies the location of the `text`. "inside"
            positions `text` inside, next to the bar end (rotated
            and scaled if needed). "outside" positions `text`
            outside, next to the bar end (scaled if needed), unless
            there is another bar stacked on this one, then the text
            gets pushed inside. "auto" tries to position `text`
            inside the bar, but if the bar is too small and no bar
            is stacked on this one the text is moved outside. If
            "none", no text appears.
        texttemplate
            Template string used for rendering the information text
            that appears on points. Note that this will override
            `textinfo`. Variables are inserted using %{variable},
            for example "y: %{y}". Numbers are formatted using
            d3-format's syntax %{variable:d3-format}, for example
            "Price: %{y:$.2f}".
            https://github.com/d3/d3-format/tree/v1.4.5#d3-format
            for details on the formatting syntax. Dates are
            formatted using d3-time-format's syntax
            %{variable|d3-time-format}, for example "Day:
            %{2019-01-01|%A}". https://github.com/d3/d3-time-
            format/tree/v2.2.3#locale_format for details on the
            date formatting syntax. Variables that can't be found
            will be replaced with the specifier. For example, a
            template of "data: %{x}, %{y}" will result in a value
            of "data: 1, %{y}" if x is 1 and y is missing.
            Variables with an undefined value will be replaced with
            the fallback value. All attributes that can be
            specified per-point (the ones that are `arrayOk: true`)
            are available. Finally, the template string has access
            to variables `value` and `label`.
        texttemplatefallback
            Fallback string that's displayed when a variable
            referenced in a template is missing. If the boolean
            value 'false' is passed in, the specifier with the
            missing variable will be displayed.
        uid
            Assign an id to this trace, Use this to provide object
            constancy between traces during animations and
            transitions.
        uirevision
            Controls persistence of some user-driven changes to the
            trace: `constraintrange` in `parcoords` traces, as well
            as some `editable: true` modifications such as `name`
            and `colorbar.title`. Defaults to `layout.uirevision`.
            Note that other user-driven trace attribute changes are
            controlled by `layout` attributes: `trace.visible` is
            controlled by `layout.legend.uirevision`,
            `selectedpoints` is controlled by
            `layout.selectionrevision`, and `colorbar.(x|y)`
            (accessible with `config: {editable: true}`) is
            controlled by `layout.editrevision`. Trace changes are
            tracked by `uid`, which only falls back on trace index
            if no `uid` is provided. So if your app can add/remove
            traces before the end of the `data` array, such that
            the same trace has a different index, you can still
            preserve user-driven changes if you give each trace a
            `uid` that stays with it as it moves.
        unselected
            :class:`plotly.graph_objects.bar.Unselected` instance
            or dict with compatible properties
        visible
            Determines whether or not this trace is visible. If
            "legendonly", the trace is not drawn, but can appear as
            a legend item (provided that the legend itself is
            visible).
        width
            Sets the bar width (in position axis units).
        x
            Sets the x coordinates.
        x0
            Alternate to `x`. Builds a linear space of x
            coordinates. Use with `dx` where `x0` is the starting
            coordinate and `dx` the step.
        xaxis
            Sets a reference between this trace's x coordinates and
            a 2D cartesian x axis. If "x" (the default value), the
            x coordinates refer to `layout.xaxis`. If "x2", the x
            coordinates refer to `layout.xaxis2`, and so on.
        xcalendar
            Sets the calendar system to use with `x` date data.
        xhoverformat
            Sets the hover text formatting rule for `x` using d3
            formatting mini-languages which are very similar to
            those in Python. For numbers, see:
            https://github.com/d3/d3-format/tree/v1.4.5#d3-format.
            And for dates see: https://github.com/d3/d3-time-
            format/tree/v2.2.3#locale_format. We add two items to
            d3's date formatter: "%h" for half of the year as a
            decimal number as well as "%{n}f" for fractional
            seconds with n digits. For example, *2016-10-13
            09:15:23.456* with tickformat "%H~%M~%S.%2f" would
            display *09~15~23.46*By default the values are
            formatted using `xaxis.hoverformat`.
        xperiod
            Only relevant when the axis `type` is "date". Sets the
            period positioning in milliseconds or "M<n>" on the x
            axis. Special values in the form of "M<n>" could be
            used to declare the number of months. In this case `n`
            must be a positive integer.
        xperiod0
            Only relevant when the axis `type` is "date". Sets the
            base for period positioning in milliseconds or date
            string on the x0 axis. When `x0period` is round number
            of weeks, the `x0period0` by default would be on a
            Sunday i.e. 2000-01-02, otherwise it would be at
            2000-01-01.
        xperiodalignment
            Only relevant when the axis `type` is "date". Sets the
            alignment of data points on the x axis.
        y
            Sets the y coordinates.
        y0
            Alternate to `y`. Builds a linear space of y
            coordinates. Use with `dy` where `y0` is the starting
            coordinate and `dy` the step.
        yaxis
            Sets a reference between this trace's y coordinates and
            a 2D cartesian y axis. If "y" (the default value), the
            y coordinates refer to `layout.yaxis`. If "y2", the y
            coordinates refer to `layout.yaxis2`, and so on.
        ycalendar
            Sets the calendar system to use with `y` date data.
        yhoverformat
            Sets the hover text formatting rule for `y` using d3
            formatting mini-languages which are very similar to
            those in Python. For numbers, see:
            https://github.com/d3/d3-format/tree/v1.4.5#d3-format.
            And for dates see: https://github.com/d3/d3-time-

            formatted using `yaxis.hoverformat`.
        yperiod
            Only relevant when the axis `type` is "date". Sets the
            period positioning in milliseconds or "M<n>" on the y
            axis. Special values in the form of "M<n>" could be
            used to declare the number of months. In this case `n`
            must be a positive integer.
        yperiod0
            Only relevant when the axis `type` is "date". Sets the
            base for period positioning in milliseconds or date
            string on the y0 axis. When `y0period` is round number
            of weeks, the `y0period0` by default would be on a
            Sunday i.e. 2000-01-02, otherwise it would be at
            2000-01-01.
        yperiodalignment
            Only relevant when the axis `type` is "date". Sets the
            alignment of data points on the y axis.
        zorder
            Sets the layer on which this trace is displayed,
            relative to other SVG traces on the same subplot. SVG
            traces with higher `zorder` appear in front of those
            with lower `zorder`.
