Generic 3D color/contour plot of parametric sweep values

I do a parametric sweep and sweep two variables (say, width=1,2,3; height=4,5,6). I select the dropdown box that says "All combinations" so that I get all combinations - i.e.
width=1 and height=4
width=1 and height=5
width=1 and height=6
width=2 and height=4
width=2 and height=5
width=2 and height=6
width=3 and height=4
width=3 and height=5
width=3 and height=6
and I solve for some global value such as total power.
Now usually what I do next is take that "total power" data and put it into matlab to make a 3d plot (2d = width and height, 3rd dimension = total power. So the 3D plot is a color plot or contour plot)
However I'd like to do that from within COMSOL. I try adding a 3D plot group to Results node, but it appears that is only designed for 3D visualizations of some value over the device geometry, not for generic 3D plots.
Can this be done in COMSOL?
Thanks

First, export your data points to matlab
Second, rearrange your data points in a proper order, for example:
x = [x1 x2....
x1 x2...
x1 x2...];
y = [y1 y1...
y2 y2...]
z = ....
You can refer to meshgrid() for this part
Finally, use the matlab function contour(x,y,z)
