Dear Gökhan,
Thanks for your reply, but unfortunately it was not entirely helpful.
The rectangle_selector.py exemple indeed seems to do what I want, by
means of a callback function, however in the example program this
function should print the rectangle coordinates to the screen but it
does nothing.
Check the shell where you called the script. It updates when select a region and release the mouse.
BTW, where is the documentation for the matplotlib.widgets classes? I
could find none.
Just browse the actual source …/lib/matplotlib/widgets.py. Classes are methods are nicely documented. I would suggest you to use IPython to access the docstrings with ease.
import matplotlib.widgets as w
w?
w.

Dear ALL,
Good morning… Here is a question that may already have been asked
(and answered), but not to my knowledge. Matplotlib’s figure windows
come with that handy navigation bar, which includes a Pan/Zoom button
and a Zoom-to-rectangle button. Once a zoom rectangle is defined on a
figure, is it possible to get the coordinates of it (that is, the
lower and upper corner coordinates which define the zoom rectangle)?
If so, how can this be done?
Thanks in advance for any reply.
With best regards,

Hi,
Search for zoom_window.py and rectangle_selector.py in your matplotlib
examples directory.
