I wanted to display a line plot with rainbow coloring based on the y-value, similar to what’s possible for surface plots. However, the ‘plot’ method does not appear to accept a ‘cmap’ argument. The closest thing I was able to find was a recipe for different colored line segments on the SciPy examples page (http://www.scipy.org/Cookbook/Matplotlib/MulticoloredLine), but that’s not really what I want - I was hoping for a continuous gradient over hundreds (possibly thousands) of points on a line. Is this possible without too much hacking?

thanks,

Nat
