Hi guys,
I have a simpler example.
Check this:
import numpy as np
import enthought.mayavi.mlab as mlab
def f(x, y):
return 1/x + y
x, y = np.mgrid[0.1:3:0.1, -2.:2.:0.01]
s = mlab.surf(x, y, f)
Pretty much if you try to plot 1/x alone it doesn't work. No surface
whatsoever appear in the window.
I started also from 0.1 so there is no -Inf value.
Is this expected or not? The surf methos can't be used with 1/x form?
Cheers,
Michele.
