[Matplotlib-users] split axis scale

Hi,

I have a plot containing two lines that are quite far apart - ie one
line oscillates around y=2, the other around y=10. The osciallations
are small, but I would like to show the detail better (while having
htem in a single plot).

So I thought it would be nice if the y-axis scale went from 1-3 then
had a break (denoted with some kind of cross mark), then went from
9-11. I tried googling but I'm not really sure what the official name
for such a thing is, if there is one.

Is it possible to get this sort of effect with matplotlib? Or can
people suggest an alternative (I guess I will look at doing 2 subplots
one above the other very close together).

Cheers

Robin
