[Matplotlib-users] [Help] Broken_barh Picking design using the OO interface

[sunzen w. <su...@gm...>]

Hi Gurus,
   I'm new to matplotlib programming, and get puzzled about designing
picking handler for broken_barh by the OO interface.
My current approach is presented as the following:
1. plot broken_barh and set picker
   pcol = axes.broken_barh(xseq, yseq, facecolors = colors)
   pcol.set_picker(True)
2. Design picking handler
   mycanvas.mpl_connect('pick_event', foo_pick)
   .....
   def foo_pick(self, event):

Could you give me any guidance?
