> I have created a runnable sample app that demonstrates the problem
Here is a much simpler 10 line sample that doesn't require wxPython and demonstrates the problem: you can't pick the red line. This seems like a bug in mpl 1.0. import matplotlib.pyplot as plt fig = plt.figure() ax = fig.add_subplot(111) ax2 = ax.twinx() line, = ax.plot([1,2,3], 'r-o', markersize=15, picker=5) line2, = ax2.plot([4,2,12], 'b-o', markersize=15, picker=5) def onpick(event): print 'picked line: ', event.artist fig.canvas.mpl_connect('pick_event', onpick) plt.show()
