Hi,
running the simple test code:
from pylab import *
X, Y = meshgrid(linspace(-3,3,11),linspace(-3,3,11))
Z = randn(*X.shape)
lev = linspace(Z.min(),Z.max(),11)[1:-1]
contourf(X,Y,Z, lev, extend='both')
contour(X,Y,Z, lev, colors='k')
show()
you will probably notice that the 'contourf' contours are not always
exactly the sames as the 'contour' contours. Why is it so? Don't contour
and contourf use the same contour constructor?
Cheers.
