I'm having trouble doing an "egg" (setuptools) install of matplotlib.

I've got a 2-D array of values that I'd like to plot onto a map with
Basemap. The latitude and longitudes for each point are stored in their
own 2-D array that matches that of the values. Can some one help with
how to do this? Looks like basemap requires a square and uniform set of

Pierre,
I will try to improve it.

This slightly modified excerpt from the new version of spy may do what
you want:
nr, nc = Z.shape
extent = [-0.5, nc-0.5, nr-0.5, -0.5]
return self.imshow(Z, interpolation='nearest',
extent=extent, origin='upper')

Hi,
I am a regular user of matplotlib since I moved from matlab to
python/numpy/scipy. Even if I find matplotlib to be a real help during
the transition from matlab to python, I must confess I found it the most
disappointing compare other packages ( essentially numpy/scipy/ipython).

Hi, I'm struggling to get an array plotted the way I want with imshow.
I have an array A which i try to plot with
e=(tdims[0], tdims[-1], wldims[-1], wldims[0])
imshow(A,extent=e)
The image displays fine in the x axis, with tdims marked correctly,
but in the yaxis the dimensions are incorrect. An

The following code in Python causes leakage of memory:
from pylab import *
import pygtk
pygtk.require('2.0')
import gtk
import matplotlib
matplotlib.use('GTKAgg') # or 'GTK'
from matplotlib.backends.backend_gt

in cntr.c to something more explicit, when x, y, and z are 2D arrays, but one
of them is complex ? Or force a downcast to float if needed ?
