Hi all,
I have defined some shortcuts I often use using pylab.ginput(). I normally
do:
> fig = pylab.figure()
fig.canvas.mpl_connect('key_press_event', on_key)
with my "on_key" function being (simplified):
> def on_key(event):
if (event.key == 'q'):
sys.exit(0)
elif (event.key == 'w'):
pylab.close(pylab.gcf())
elif (event.key == 'd'):
print "Please click two points to get the distance and slope."
points = pylab.ginput(n=2, show_clicks=True)
[...]
pylab.plot([points[0][0], points[1][0]], [points[0][1],
> points[1][1]], '+r', lw=1.0)
pylab.plot([points[0][0], points[1][0]], [points[0][1],
> points[1][1]], '--r', lw=1.0)
pylab.draw()
I'm plotting two markers where the user clicked and a line between them.
This works fine, except when there is multiple subplots. I can correctly
select points and get their position, but the plot commands will put the
markers+line in the last subplot. I tried using "pylab.gca().plot()" but
gca() always returns the last axes.
My question is, how can I plot on the axes the user clicked on?
Thank you!
