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. > > I would like to contour based on data divisions. > > For instance, perhaps I'd like to use a contour or color-fill > (contourf) every 2 units.
