===========
Zoom Window
===========

This example shows how to connect events in one window, for example, a mouse
press, to another figure window.

If you click on a point in the first window, the z and y limits of the second
will be adjusted so that the center of the zoom in the second window will be
the (x, y) coordinates of the clicked point.

Note the diameter of the circles in the scatter are defined in points**2, so
their size is independent of the zoom.

.. note::
    This example exercises the interactive capabilities of Matplotlib, and this
    will not appear in the static documentation. Please run this code on your
    machine to see the interactivity.

    You can copy and paste individual parts, or download the entire example
    using the link at the bottom of the page.
