Re: [matplotlib-devel] auto-rotating text and plotyy
Hi, Sorry I didn't respond to this immediately - I have had my mind on other things. plotyy is basically a wrapper around twinx that provides a bit of extra/built-in functionality. The idea is that you have two curves with similar x values, but different y that you want to plot together. It plots them both using twinx, but to help with visualisation, it changes the color of each curve and associated axis so that they are easy to distinguish (e.g., left blue, right green). This is also similar to a matlab function of the same name, so it helps us matlab converts out. An example of using this function might be: x = linspace(0,pi,20) y = sin(x) x2 = linspace(0.1,pi-0.1,20) y2 = cos(x2) axs,h1,h2=plotyy(x,y,x2,y2) axs is a list with [ax1,ax2]. As is evident from the code itself, there isn't too much beyond what twinx already does, but this code aids matlab compatibility and also the recursive handle property change is useful. But this recursive code could be extricated to provide a general setp_recursive function that would change a property on an object and all its children (that have that property) if that is of interest.

[matplotlib-devel] Alternate lasso: click to form polygon
I wanted something more precise (and easier on the carpal tunnel) than
the included Lasso widget. Inspired by the existing Lasso, I forked
out an alternate approach that creates a polygon with mouse clicks and
returns a list of vertices to a callback function.
See the attached for a demo. It's been tested with WxAgg running off
recent svn. I'm using idle_event, which isn't mentioned in the docs
for the released version.
If there's interest, I'll put together a patch to add this to widgets.py.
Thanks,
Eric B

Yes, there is interest--we should have this functionality if it can work on all interactive backends. I gave it a quick try with gtk backend. The polygon is drawn based on clicks, but nothing gets printed. Is this expected?
