Description
I am using IPython 2.3.1 and ab549ac. To reproduce, run IPython and %paste the code below. Click on the figure and then press the 'S' key. The traceback below is printed and the figure becomes unresponsive.
import matplotlib
import itertools
import numpy as np
matplotlib.use('webagg')
import matplotlib.pyplot as plt
plt.close('all')
fig, ax = plt.subplots()
x = np.linspace(0,10,10000)
y = np.sin(x)
ln, = ax.plot(x,y)
evt = []
colors = iter(itertools.cycle(['r', 'g', 'b', 'k', 'c']))
def on_event(event):
evt.append(event)
ln.set_color(next(colors))
fig.canvas.draw()
fig.canvas.draw_idle()
fig.canvas.mpl_connect('button_press_event', on_event)
plt.show()ERROR:tornado.application:Uncaught exception in /1/ws
