            number of data points lying inside the bins). If
            "percent" / "probability", the span of each bar
            corresponds to the percentage / fraction of occurrences
            with respect to the total number of sample points
            (here, the sum of all bin HEIGHTS equals 100% / 1). If

            the bin interval (here, the sum of all bin AREAS equals
            the total number of sample points). If *probability
            density*, the area of each bar corresponds to the

            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

            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 variable `z` 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.
        hovertemplatesrc
            Sets the source reference on Chart Studio Cloud for

            array of strings, not numbers or any other type.
        idssrc
            Sets the source reference on Chart Studio Cloud for
            `ids`.
        legend
            Sets the reference to a legend to show this trace in.
            References to these legends are "legend", "legend2",

            with "reversed" `legend.traceorder` they are on
            bottom/right side. The default legendrank is 1000, so

            items before all unranked items, and ranks greater than
            1000 to go after all unranked items. When having

            layout.
        legendwidth
            Sets the width (in px or fraction) of the legend for
            this trace.

            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.
        metasrc
            Sets the source reference on Chart Studio Cloud for
            `meta`.
        name
            Sets the trace name. The trace name appears as the
            legend item and on hover.
        nbinsx
            Specifies the maximum number of desired bins. This
            value will be used in an algorithm that will decide the
            optimal bin size such that the histogram best
            visualizes the distribution of the data. Ignored if
            `xbins.size` is provided.
        nbinsy
            Specifies the maximum number of desired bins. This
            value will be used in an algorithm that will decide the
            optimal bin size such that the histogram best
            visualizes the distribution of the data. Ignored if
            `ybins.size` is provided.
        ncontours
            Sets the maximum number of contour levels. The actual
            number of contours will be chosen automatically to be
            less than or equal to the value of `ncontours`. Has an
            effect only if `autocontour` is True or if
            `contours.size` is missing.
        opacity
            Sets the opacity of the trace.
        reversescale
            Reverses the color mapping if true. If true, `zmin`
            will correspond to the last color in the array and
            `zmax` will correspond to the first color.
        showlegend
            Determines whether or not an item corresponding to this
            trace is shown in the legend.
        showscale
            Determines whether or not a colorbar is displayed for
            this trace.
        stream
            :class:`plotly.graph_objects.histogram2dcontour.Stream`
            instance or dict with compatible properties
        textfont
            For this trace it only has an effect if `coloring` is
            set to "heatmap". Sets the text font.
        texttemplate
            For this trace it only has an effect if `coloring` is
            set to "heatmap". 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 `x`, `y`, `z` and `text`.
        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.
        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).
        x
            Sets the sample data to be binned on the x axis.
        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.
        xbingroup
            Set a group of histogram traces which will have
            compatible x-bin settings. Using `xbingroup`,
            histogram2d and histogram2dcontour traces  (on axes of
            the same axis type) can have compatible x-bin settings.
            Note that the same `xbingroup` value can be used to set

            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`.
        xsrc
            Sets the source reference on Chart Studio Cloud for
            `x`.
        y
            Sets the sample data to be binned on the y axis.
        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.
        ybingroup
            Set a group of histogram traces which will have
            compatible y-bin settings. Using `ybingroup`,
            histogram2d and histogram2dcontour traces  (on axes of
            the same axis type) can have compatible y-bin settings.
            Note that the same `ybingroup` value can be used to set

            formatted using `yaxis.hoverformat`.
        ysrc
            Sets the source reference on Chart Studio Cloud for
            `y`.
        z
            Sets the aggregation data.
        zauto
            Determines whether or not the color domain is computed
            with respect to the input data (here in `z`) or the
            bounds set in `zmin` and `zmax` Defaults to `false`
            when `zmin` and `zmax` are set by the user.
        zhoverformat
            Sets the hover text formatting rulefor `z`  using d3
            formatting mini-languages which are very similar to
            those in Python. For numbers, see: https://github.com/d
            3/d3-format/tree/v1.4.5#d3-format.By default the values
            are formatted using generic number format.
        zmax
            Sets the upper bound of the color domain. Value should
            have the same units as in `z` and if set, `zmin` must
            be set as well.
        zmid
            Sets the mid-point of the color domain by scaling
            `zmin` and/or `zmax` to be equidistant to this point.
            Value should have the same units as in `z`. Has no
            effect when `zauto` is `false`.

        Construct a new Histogram2dContour object

        The sample data from which statistics are computed is set in
        `x` and `y` (where `x` and `y` represent marginal
        distributions, binning is set in `xbins` and `ybins` in this
        case) or `z` (where `z` represent the 2D distribution and
        binning set, binning is set by `x` and `y` in this case). The

        Parameters
        ----------
        arg
            dict of properties compatible with this constructor or
            an instance of
            :class:`plotly.graph_objs.Histogram2dContour`
        autobinx
            Obsolete: since v1.42 each bin attribute is auto-
            determined separately and `autobinx` is not needed.
            However, we accept `autobinx: true` or `false` and will
            update `xbins` accordingly before deleting `autobinx`
            from the trace.
        autobiny
            Obsolete: since v1.42 each bin attribute is auto-
            determined separately and `autobiny` is not needed.
            However, we accept `autobiny: true` or `false` and will
            update `ybins` accordingly before deleting `autobiny`
            from the trace.
        autocolorscale
            Determines whether the colorscale is a default palette
            (`autocolorscale: true`) or the palette determined by
            `colorscale`. In case `colorscale` is unspecified or
            `autocolorscale` is true, the default palette will be
            chosen according to whether numbers in the `color`
            array are all positive, all negative or mixed.
        autocontour
            Determines whether or not the contour level attributes
            are picked by an algorithm. If True, the number of
            contour levels can be set in `ncontours`. If False, set
            the contour level attributes in `contours`.
        bingroup
            Set the `xbingroup` and `ybingroup` default prefix For
            example, setting a `bingroup` of 1 on two histogram2d
            traces will make them their x-bins and y-bins match
            separately.
        coloraxis
            Sets a reference to a shared color axis. References to
            these shared color axes are "coloraxis", "coloraxis2",
            "coloraxis3", etc. Settings for these shared color axes
            are set in the layout, under `layout.coloraxis`,
            `layout.coloraxis2`, etc. Note that multiple color
            scales can be linked to the same color axis.
        colorbar
            :class:`plotly.graph_objects.histogram2dcontour.ColorBa
            r` instance or dict with compatible properties
        colorscale
            Sets the colorscale. The colorscale must be an array
            containing arrays mapping a normalized value to an rgb,
            rgba, hex, hsl, hsv, or named color string. At minimum,
            a mapping for the lowest (0) and highest (1) values are
            required. For example, `[[0, 'rgb(0,0,255)'], [1,
            'rgb(255,0,0)']]`. To control the bounds of the
            colorscale in color space, use `zmin` and `zmax`.
            Alternatively, `colorscale` may be a palette name
            string of the following list: Blackbody,Bluered,Blues,C
            ividis,Earth,Electric,Greens,Greys,Hot,Jet,Picnic,Portl
            and,Rainbow,RdBu,Reds,Viridis,YlGnBu,YlOrRd.
        contours
            :class:`plotly.graph_objects.histogram2dcontour.Contour
            s` instance or dict with compatible properties
        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
        customdatasrc
            Sets the source reference on Chart Studio Cloud for
            `customdata`.
        histfunc
            Specifies the binning function used for this histogram
            trace. If "count", the histogram values are computed by
            counting the number of values lying inside each bin. If
            "sum", "avg", "min", "max", the histogram values are
            computed using the sum, the average, the minimum or the
            maximum of the values lying inside each bin
            respectively.
        histnorm
            Specifies the type of normalization used for this
            histogram trace. If "", the span of each bar
            corresponds to the number of occurrences (i.e. the
            number of data points lying inside the bins). If
            "percent" / "probability", the span of each bar
            corresponds to the percentage / fraction of occurrences
            with respect to the total number of sample points
            (here, the sum of all bin HEIGHTS equals 100% / 1). If
            "density", the span of each bar corresponds to the
            number of occurrences in a bin divided by the size of
            the bin interval (here, the sum of all bin AREAS equals
            the total number of sample points). If *probability
            density*, the area of each bar corresponds to the
            probability that an event will fall into the
            corresponding bin (here, the sum of all bin AREAS
            equals 1).
        hoverinfo
            Determines which trace information appear 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.
        hoverinfosrc
            Sets the source reference on Chart Studio Cloud for
            `hoverinfo`.
        hoverlabel
            :class:`plotly.graph_objects.histogram2dcontour.Hoverla
            bel` 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 variable `z` 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.
        hovertemplatesrc
            Sets the source reference on Chart Studio Cloud for
            `hovertemplate`.
        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.
        idssrc
            Sets the source reference on Chart Studio Cloud for
            `ids`.
        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.histogram2dcontour.Legendg
            rouptitle` 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.
        line
            :class:`plotly.graph_objects.histogram2dcontour.Line`
            instance or dict with compatible properties
        marker
            :class:`plotly.graph_objects.histogram2dcontour.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.
        metasrc
            Sets the source reference on Chart Studio Cloud for
            `meta`.
        name
            Sets the trace name. The trace name appears as the
            legend item and on hover.
        nbinsx
            Specifies the maximum number of desired bins. This
            value will be used in an algorithm that will decide the
            optimal bin size such that the histogram best
            visualizes the distribution of the data. Ignored if
            `xbins.size` is provided.
        nbinsy
            Specifies the maximum number of desired bins. This
            value will be used in an algorithm that will decide the
            optimal bin size such that the histogram best
            visualizes the distribution of the data. Ignored if
            `ybins.size` is provided.
        ncontours
            Sets the maximum number of contour levels. The actual
            number of contours will be chosen automatically to be
            less than or equal to the value of `ncontours`. Has an
            effect only if `autocontour` is True or if
            `contours.size` is missing.
        opacity
            Sets the opacity of the trace.
        reversescale
            Reverses the color mapping if true. If true, `zmin`
            will correspond to the last color in the array and
            `zmax` will correspond to the first color.
        showlegend
            Determines whether or not an item corresponding to this
            trace is shown in the legend.
        showscale
            Determines whether or not a colorbar is displayed for
            this trace.
        stream
            :class:`plotly.graph_objects.histogram2dcontour.Stream`
            instance or dict with compatible properties
        textfont
            For this trace it only has an effect if `coloring` is
            set to "heatmap". Sets the text font.
        texttemplate
            For this trace it only has an effect if `coloring` is
            set to "heatmap". 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 `x`, `y`, `z` and `text`.
        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.
        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).
        x
            Sets the sample data to be binned on the x axis.
        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.
        xbingroup
            Set a group of histogram traces which will have
            compatible x-bin settings. Using `xbingroup`,
            histogram2d and histogram2dcontour traces  (on axes of
            the same axis type) can have compatible x-bin settings.
            Note that the same `xbingroup` value can be used to set
            (1D) histogram `bingroup`

        xhoverformat
            Sets the hover text formatting rulefor `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`.
        xsrc
            Sets the source reference on Chart Studio Cloud for
            `x`.
        y
            Sets the sample data to be binned on the y axis.
        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.
        ybingroup
            Set a group of histogram traces which will have
            compatible y-bin settings. Using `ybingroup`,
            histogram2d and histogram2dcontour traces  (on axes of
            the same axis type) can have compatible y-bin settings.
            Note that the same `ybingroup` value can be used to set
            (1D) histogram `bingroup`
        ybins

            instance or dict with compatible properties
        ycalendar
            Sets the calendar system to use with `y` date data.
        yhoverformat
            Sets the hover text formatting rulefor `y`  using d3
            formatting mini-languages which are very similar to

            display *09~15~23.46*By default the values are
            formatted using `yaxis.hoverformat`.
        ysrc
            Sets the source reference on Chart Studio Cloud for
            `y`.
        z
            Sets the aggregation data.
        zauto
            Determines whether or not the color domain is computed
            with respect to the input data (here in `z`) or the
            bounds set in `zmin` and `zmax` Defaults to `false`
            when `zmin` and `zmax` are set by the user.
        zhoverformat
            Sets the hover text formatting rulefor `z`  using d3
            formatting mini-languages which are very similar to
            those in Python. For numbers, see: https://github.com/d
            3/d3-format/tree/v1.4.5#d3-format.By default the values
            are formatted using generic number format.
        zmax
            Sets the upper bound of the color domain. Value should
            have the same units as in `z` and if set, `zmin` must
            be set as well.
        zmid
            Sets the mid-point of the color domain by scaling
            `zmin` and/or `zmax` to be equidistant to this point.
            Value should have the same units as in `z`. Has no
            effect when `zauto` is `false`.
        zmin
            Sets the lower bound of the color domain. Value should
            have the same units as in `z` and if set, `zmax` must
            be set as well.
        zsrc
            Sets the source reference on Chart Studio Cloud for
            `z`.
