[Matplotlib-users] small patch to enable formatters for contour line labels

[Daniel H. <dh...@gm...>]

The function "clabel" does not allow the use of formatters for the label;
this small patch enables their use, so that one can pass in any subclass of
ticker.Formatter in the 'fmt' argument.

Replace the following in contour.py:

   def get_text(self, lev, fmt):
       "get the text of the label"
       if cbook.is_string_like(lev):
           return lev
       else:
           if isinstance(fmt,dict):
               return fmt[lev]
           else:
               return fmt%lev

With the following:

   def get_text(self, lev, fmt):
       "get the text of the label"
       if cbook.is_string_like(lev):
           return lev
       else:
           if isinstance(fmt,dict):
               return fmt[lev]
           elif isinstance(fmt,ticker.Formatter):
               return fmt(lev)
           else:
               return fmt%lev


As you can see, there is only a two line change, but it does enable
formatters.  Perhaps one of the devs can put this in?
