Hi,
ipython 3.0.0-dev
matplotlib 1.3.1
GTKAgg backend
mac osx 10.9
If I create a pick_event on an axvline (with picker=6), there is no
problem triggering the pick event the first time the figure is shown (or
many times if I _don't_ zoom or pan). But if I then zoom in or pan
(using the toolbar tools) the pick_event function stops triggering.
The button_press_event that I also created still works after
zooming/panning. The pick_event still doesn't work even if I disconnect
all the events and recreate them (by creating a new object).
I have to close the figure and make a new one to make the pick work
again. The button_press_event always works.
This is the bottom of the plotting function:
# plot axvlines here... etc.
global cids
# remove any previous connections
for i in cids:
gcf().canvas.mpl_disconnect(i)
cids = []
cids.append(gcf().canvas.mpl_connect('pick_event',self.pick))
cids.append(gcf().canvas.mpl_connect('button_press_event',self.click))
draw()
def pick(self, event):
thisline = event.artist
xdata, ydata = thisline.get_data()
print xdata[0]
def click(self, event):
print "clicked"
Anybody got a clue what's going on? Does the Line2D get deleted and
recreated without the picker enabled?
