Hello Robert,
I studied delaunay and mlab.griddata a bit while converting tinterp and
saw the

I should read entire posts before sending people down the wrong
pathways. I just happened to be working on a Python equivalent to MATLAB
"triplot" stuff when I read your subject line and made the wrong
assumptions. That program does just plot the edges, as you noted.
I have attached a python p

Here is an example using matplotlib.delaunay, which automatically
returns the edges and triangules:
import matplotlib.delaunay as delaunay
import matplotlib.pyplot as pp
#generate points
npts=41
xpt=sp.random.random_sample(npts)
ypt=sp.random.random_sample(npts)
#create triangulation
