[Scilab-users] color under a curve

[grivet]

Thank you Adrien and Christophe.

The code provided by Christophe is specially simple and elegant, but assumes
the function to be strictly positive. Filled areas are different when I 
change
x to x = linspace(-2*%pi,2*%pi,100).
For my purposes, it seems best to use xfpoly() for each region where the
function has a constant sign. The drawback is that color choices are not
as versatile as with plot().
