The 'hoverlabel' property is an instance of Hoverlabel
that may be specified as:
  - An instance of :class:`plotly.graph_objs.histogram2dcontour.Hoverlabel`
  - A dict of string/value properties that will be passed
    to the Hoverlabel constructor

    Supported dict properties:

        align
            Sets the horizontal alignment of the text
            content within hover label box. Has an effect
            only if the hover label text spans more two or
            more lines
        alignsrc
            Sets the source reference on Chart Studio Cloud
            for `align`.
        bgcolor
            Sets the background color of the hover labels
            for this trace
        bgcolorsrc
            Sets the source reference on Chart Studio Cloud
            for `bgcolor`.
        bordercolor
            Sets the border color of the hover labels for
            this trace.
        bordercolorsrc
            Sets the source reference on Chart Studio Cloud
            for `bordercolor`.
        font
            Sets the font used in hover labels.
        namelength
            Sets the default length (in number of
            characters) of the trace name in the hover
            labels for all traces. -1 shows the whole name
            regardless of length. 0-3 shows the first 0-3
            characters, and an integer >3 will show the
            whole name if it is less than that many
            characters, but if it is longer, will truncate
            to `namelength - 3` characters and add an
            ellipsis.
        namelengthsrc
            Sets the source reference on Chart Studio Cloud
            for `namelength`.
