hey guys... i got it... u can use contour(x,y,z)... as in x=load('
urfile1.dat'), y=load('urfile2.dat), z=load('urfile3.dat').... and then type
out the above.... for details about the parameters x,y,z see... .
http://www.scilab.org/product/man-eng/graphics/contour.htm .... so
matplotlib CAN plot a contour from discrete points!!!.... ive tried it and
it works...
