matplotlib-users Mailing List for matplotlib

I'm trying to get matplotlib to make a 600x300 png, but matplotlib won't
let me; it keeps making a 612x312 png instead.  Here's a sample script
that has the problem on my system:

figure(figsize=(6., 3.))
plot(arange(10))
savefig('test.png', dpi=100.)

If I set dpi to 50., it makes a 312x162 png.  It appears to be adding a 6
pixel border to the edge of all the pngs.  How do I get rid of it?

Windows XP SP2, Python 2.5, matplotlib 0.90.

I'm going to advise you to not try to do that. MPL really isn't a GUI 
toolkit, there there are a number of very nice and complete GUI toolkits 
that MPL works just great with. It will require a bit of learning up 
front, but you'll get a much better result, and probably less pain in 
the process. My thoughts:

For Cross platform (Windows, *nix, OS-X): wxPython or pyQT. Tk's OK too, 
but at least until recently, not very native or robust on OS-X.

For *nix only: PyGTK

For OS-X only: Maybe pyObjC, but only if MPL is working OK with the 
Cocoa back-end -- or has development stalled there?

See the "embedding in ..." examples, and be sure to check out wxMPL if 
you want to use wxPython.

Hello everybody,

I tried useing matplotlib as a GUI for my programs. I'd like to incorporate 
things like Buttons, Sliders, RadioButtons and so on from 
matplotlib.widgets, but missed a prompt (i.e. a field to input text and/or 
numbers).

My question is: Is there already a text-input-field in one of the mpl modules?

Best regards and thanks in advance for any hints,

Teng:

Have you tried

contourf(X, Y, Z, v1, cmap=cm.pink_r)
