Hi all, Given a set of points (x_i,y_i,z_i) is it possible to plot y_i versus x_i with a varying color corresponding to the magnitude of z_i ? Nils |

Nils We can't do this in 3D, but you can do it in 2D with a pseudo color plot. If your z-y data do not lie on a grid, you need to interpolate them onto a grid first http://www.scipy.org/Wiki/Cookbook/Matplotlib/Gridding_irregularly_spaced_data JDH |

It's in the sandbox: scipy/Lib/sandbox/delaunay Go to this directory, and install with the usual python setup.py build; python setup.py install I'll change the wiki so this is more clear. -Rob.

The preferred way to build packages in the sandbox is to uncomment (or add) the appropriate line in scipy/Lib/sandbox/setup.py and rebuild scipy. They should then be referred to as scipy.sandbox.delaunay, for example. -- Robert Kern rob...@gm...
