Matlab 3D Plot (surf) fills in empty gaps automatically

I'm using surf() to plot a portion of a sphere; basically a shell of a certain shape that is on top of a sphere. More specifically, it is the workspace plot of spherical joint with color representing the resolution of the joint at that point.
Anyways, the shape is unique, but surf() automatically fills in gaps that should not be there. I'm guess it might be the order that it is plotted? Is there any way to prevent Matlab from doing this?
I think it is obvious in the pictures what should not be there (the blue portion)...
Also, it seems to mess up the color coding as well. The dark blue should be at the bottom edges of the shell; instead Matlab assigns it to the surface used to fill the gaps.
Thanks!

How are you telling surf() that data should not be there?
The results you are showing are consistent with you having initialized a matrix to 60, writing data into part of it, and then surf()'ing the whole thing.

Set the Z data that you don't want to be plotted to NaN.
But let the X,Y data remain what they are; I mean don't set X,Y to NaN.
This shall work.
