Assuming that this is a regular grid (so that using meshgrid makes sense)
you can
using pcolor:
m.pcolormesh(x,y,dat)
Unfortunately, this didn't work. I got the error message (using the
example data from my previous post):

Dear ALL,
Good morning! Here am I again with the first (and perhaps simpler)
part of a potentially long question on plotting gridded data using MPL
(*and* Basemap).
Most examples I have found of plotting gridded data (using either
MATLAB or MPL) depict highly

Mauro: The shape of x, y, and dat must all be (nlats, nlons).
I tried to do:
coords = numpy.loadtxt('grid.dat')
lon = coords[:,0]
lat = coords[:,1]
dat = coords[:,2]
X, Y = numpy.meshgrid(lon, lat)

Dear Scott Jeff,
Sorry for the delay in replying, I was off office for a while.

As Jeff noted earlier, the number of elements in an array can't be
increased simply by reshaping it, so the error message isn't too
mysterious, if carefully
