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
If I'm not mistaken, you might be able to write a Transform (http://matplotlib.sourceforge.net/devel/transformations.html) to do this, although I'm not sure how you'd render the split-mark. I don't really know these things though, just a thought. - Ben On Fri, 2008年11月28日 at 13:09 +0000, Robin wrote: > 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.

I suggest using twinx(); the scale for one line will be on the left, the scale for the other on the right. You can make the scale colors match the line colors, if you want to. I just updated examples/api/two_scales.py to show this.

Hmmm, not here: http://matplotlib.sourceforge.net/examples/api/two_scales.html And here the test on the y-axes does not display properly on the posted figures. But I like the idea. Alan Isaac `

The revised example is attached. > And here the test on the y-axes does not display properly on the > posted figures. That's puzzling. It looks like some odd rcParams settings must have been used when the figures were generated for the web page.

Obvious once you see it.
Nice.
