docstr: Sets the font of the range selector button text.
  
  The 'font' property is an instance of Font
  that may be specified as:
    - An instance of :class:`plotly.graph_objs.layout.xaxis.rangeselector.Font`
    - A dict of string/value properties that will be passed
      to the Font constructor
  
      Supported dict properties:
          
          color
  
          family
              HTML font family - the typeface that will be
              applied by the web browser. The web browser
              will only be able to apply a font if it is
              available on the system which it operates.
              Provide multiple font families, separated by
              commas, to indicate the preference in which to
              apply fonts if they aren't available on the
              system. The Chart Studio Cloud (at
              https://chart-studio.plotly.com or on-premise)
              generates images on a server, where only a
              select number of fonts are installed and
              supported. These include "Arial", "Balto",
              "Courier New", "Droid Sans",, "Droid Serif",
              "Droid Sans Mono", "Gravitas One", "Old
              Standard TT", "Open Sans", "Overpass", "PT Sans
              Narrow", "Raleway", "Times New Roman".
