Use mpl events -- they work across user interface toolkits and handle
stuff like which axes did you click in and what are the data
coordinates
def onclick(event):
print 'axes', event.inaxes
if event.inaxes is None: return
print 'canvas', event.x, event.y
print 'data', event.xdata, event.ydata
cid = fig.canvas.mpl_connect('button_press_event', onclick)
See matplotlib.backend_bases.Event and derived classes for details on
available attributes. See
matplotlib.backend_bases.FigureCanvasBase.mpl_connect for details on
valid signals,
