Re: [Matplotlib-users] Selectable contour(f) divisions
Hi Bruce, why don't you use contour as in the following ;-) contour(X,Y,Z,V) # - draw contour lines at the values specified in sequence *V* like in x, y = np.meshgrid(np.linspace(0, 1, 100), np.linspace(0, 1, 50)) z = x**4 - x**2 + np.sin(y) contour(x, y, z, [-0.2, 0.0, 0.2, 0.4, 0.6, 0.8]) Kind regards, Matthias On Thursday 11 February 2010 21:58:15 Bruce Ford wrote: In using the contour as in: contour(X,Y,Z,N) N is a number of automatically chosen levels.

Re: [Matplotlib-users] Selectable contour(f) divisions
Thanks for this. I didn't realize that N could be an array and contour would know that these are the levels desired. I found similar in an example, but not in the contour documentation.

I found similar in an example, but not in the contour documentation. Just a remark: I use the help of IPython to investigate the doc-strings of matplotlib-functions. The input contour? tells me :: contour(Z,V) contour(X,Y,Z,V) draw contour lines at the values specified in sequence *V* Kind regards, Matthias Thanks so much!
