 Customized Colorbars
 ====================
 
-:class:`~matplotlib.colorbar.ColorbarBase` derives from
-:mod:`~matplotlib.cm.ScalarMappable` and puts a colorbar in a specified axes,
-so it has everything needed for a standalone colorbar. It can be used as-is to
-make a colorbar for a given colormap; it does not need a mappable object like
-an image. In this tutorial we will explore what can be done with standalone
-colorbar.
