Sorry for spamming, but I have another addition to
BlockingMouseInput.add_click, that fixes the problem of the graphics jumping
around while ginputting. This makes it much easier to zoom in on an imshow()
plot and click a bunch of points, for example (it used to zoom all the way
out!):
def add_click(self,event):
"""
This add the coordinates of an event to the list of clicks
"""
self.clicks.append((event.xdata,event.ydata))
verbose.report("input %i: %f,%f" %
(len(self.clicks),event.xdata, event.ydata))
# If desired plot up click
if self.show_clicks:
# make sure we don't mess with the axes zoom
xlim = event.inaxes.get_xlim()
ylim = event.inaxes.get_ylim()
# plot the clicks
self.marks.extend(
event.inaxes.plot([event.xdata,], [event.ydata,], 'r+') )
# before we draw, make sure to reset the limits
event.inaxes.set_xlim(xlim)
event.inaxes.set_ylim(ylim)
self.fig.canvas.draw()
