I'm trying again to understand how to plot scattered data from array into contour graph. I looked at http://www.scipy.org/Cookbook/Matplotlib/Gridding_irregularly_spaced_data and I understand I have to grid my data. However, in most samples the plot is of a function. Let's say I want to plot some geological data, suppose water table head, and I have the following 3D aray x y head head = ((0, 0, 10), (1, 0, 13), (2, 0, 11), (3, 0, 12), (1, 2, 11)) matplotlib has lot's of restrictions about how I can plot and interpolate the data, which causes a lot of confusion in my side... I'll be happy if someone could supply me a clue of how to plot contours of data which comes in arrays or raster format and not an equation. Thanks, Oz
