Hi Eric, This shows what I'm talking about:
-------------------- from pylab import * delta = 0.025 x = arange(-3.0, 3.0, delta) y = arange(-2.0, 2.0, delta) X, Y = meshgrid(x, y) Z1 = bivariate_normal(X, Y, 1.0, 1.0, 0.0, 0.0) Z2 = bivariate_normal(X, Y, 1.5, 0.5, 1, 1) # difference of Gaussians Z = 10.0 * (Z2 - Z1) contourf(X, Y, sin(Y)*cos(X), alpha=0.2) hot() contour(X, Y, Z, 6, linewidths=4, colors=('r', 'green', 'blue', (1,1,0), '#afeeee', '0.5'), alpha=0.4) show() ------------------- On Thursday 31 August 2006 13:50, Eric Firing wrote: > Scott, > > Please send a minimal example that I can use as a test case.
