What is the best way to generate a contour plot from a set of
non-uniformly sampled data (i.e., the datapoints do not lie on the
points of a rectangular grid but are randomly distributed)?



Nikolaus: You can either use mlab.griddata to interpolate the data to a
regular grid, or use pyplot.tricontour to perform a delaunay
triangulation and contour the resulting triangle values.

Fantastic, thanks!
