> 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()
