        Parameters
        ----------
        arg
            dict of properties compatible with this constructor or
            an instance of plotly.graph_objs.Bar
        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.
        basesrc
            Sets the source reference on plot.ly for  base .
        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
        customdatasrc
            Sets the source reference on plot.ly for  customdata .
        dx
            Sets the x coordinate step. See `x0` for more info.

            events are still fired.

            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.
        hovertextsrc

            axis units). In *group* barmode, traces that set
            *offset* will be excluded and drawn in *overlay* mode
            instead.
        offsetsrc
            Sets the source reference on plot.ly for  offset .
        opacity
            Sets the opacity of the trace.
