Hi
I plotted the result of a function f(x,y) on each point of a hypar surface z = k*x*y.
Is there a possibility to plot the hypar surface in a non orthogonal coordinate system, with a corner between x and y not equal to 90°. But with the z-axis still perpenidular to the x-y plane.
Is it possible with 'patch' or something?
Thanks in advance.

Not trying to be facetious, but why do you want to do that? You could hide the orthogonal axes, create some custom ones (only for visualization), transform your data and plot it again. Sort of like this.

first of all, i want to plot the hypar containing z points z = k*x2*y2 with x2 axis en y2 axis making an random corner omega...ie. 120°. So the z points are calculated on a non orthogonal grid of points (x2,y2).
x = x2*cosd(alpha) - y2*sind(alpha) y = y2*cosd(alpha) - x2*sind(alpha)
with omega = 90° + alpha + alpha
Is there a possibility to do this?
