Hi everyone,
Here is a script that creates a graph with a y-axis break. I went with a
suggestion from Darren to use two axes and draw a break symbol in between
them. The advantage of two axes is that you can pan them independently (plus
it's probably easier). It shows roughly what I think it should look like, but
I still have to improve a few things. So I have a few questions:
- how can I hide the y-ticks in the middle of the graph (so hide only the
ticks on the top y-axis of the lower axes while leaving the ones at the
bottom there?
- Can I somehow use a transAxes transform so the axis break symbol (now
implemented as a LineCollection) stays in the same position when panning? Is
a LineCollection the best choice? I tried with a Patch class, the problem is
that the verts of this symbol are not connected.

independent control of the lines that surround the white axes box (the
left and right y-axis lines and the upper and lower x-axis lines. It
is a long-standing wish to be able to control these independently of
the axes box, and this would be a good place for you to start. See
axis.py and axes.py.JDH
