Feature Proposal

allow artists and proxy objects to define their own legend handler

background

Currently one has to define a handler map with an object if you want to get your own proxy legend entry. It needs to provide an object with only the methodlegend_artist. It would be a lot easier if if any proxy object used in the legend - or any artist - defining their ownlegend_artist method, that is being used. At the very least if there is no handler in the handler list for this object, but maybe even overwriting the handler map. For the former, in legend.py one would only need to add in the routine

defget_legend_handler(legend_handler_map,orig_handle):

The extra lines:

ifhasattr(orig_handle,'legend_artist'):returnorig_handle

before the

returnNone

if added at the beginning of the routine, it would overwrite the map. I assume not even the former is very likely to affect much existing code.
