class_docstr: This is a mixin class to support scalar data to RGBA mapping.
  The ScalarMappable makes use of data normalization before returning
  RGBA colors from the given colormap.
docstr: return the colormap
docstr_tok: ["return","the","colormap"]
code: def get_cmap(self):
      "return the colormap"
