Hi,
I've recently come accross an issue when working on an interactive
marker toggling callback. The problem is illustrated below:
import matplotlib.pyplot as plt
fig = plt.figure()
ax = fig.add_subplot(111)
line, = ax.plot(range(10), range(10))
# uncomment next line to reproduce bug
# line.set_marker('d')
legend = ax.legend([line], ['foo'])
legend_line, = legend.get_lines()
fig.show()
raw_input('press enter to clear marker')
line.set_marker('')
legend_line.set_marker('')
fig.canvas.draw()
raw_input('press enter to set marker')
line.set_marker('d')
legend_line.set_marker('d')
fig.canvas.draw()
raw_input('press enter to exit')
So when I add a line object to the legend *without marker*, the update
works fine both on data and legend line, but *with marker* it does not
refresh the legend line. I consider it as a bug, please tell me if I'm
doing something wrong.
python 2.7.4 win32
matplotlib 1.2.1
Thanks,
Gregorio
