            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.
        stream
            plotly.graph_objs.histogram.Stream instance or dict
            with compatible properties
        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.
        textsrc
            Sets the source reference on plot.ly for  text .
        uid

        unselected
            plotly.graph_objs.histogram.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).
        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.
        xbins
            plotly.graph_objs.histogram.XBins instance or dict with
            compatible properties
        xcalendar
            Sets the calendar system to use with `x` date data.
        xsrc
            Sets the source reference on plot.ly 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.
        ybins
            plotly.graph_objs.histogram.YBins instance or dict with
            compatible properties
        ycalendar
            Sets the calendar system to use with `y` date data.
        ysrc
            Sets the source reference on plot.ly for  y .
