Matlab Contour Plots to HiQ

I have created graphs using various functions within Matlab, which I need to

translate to HiQ for other system requirements. My problem is that one of

the key graphs is a contour graph which shows the specific layer(s). The

Matlab command is simple:

_______

v=[.8 .8];

contourf(X,Y,Z,v)

__________

X,Y,Z are matrices representing a sphere and 'v' is a vector at a specific

contour level. The end result is a filled contour showing a single layer.

Any help would be greatly appreciated.
