[Scilab-users] 2D contour for a non-rectangular region.

[Ganesh Diwan]

How does one go about plotting a 2D contour for a  non-rectangular region?
I have a data file that contains XY data and the potential values at the
points. The region of interest is not rectangular.
Is there a way to generate a contour plot of such a data with Scilab?
Many thanks in advance for help.
