Contour plots are 2D-images, representing 3D data. The color is the representation of the z coordinate.

It is only possible to plot data files, which must have the following structure:
/contourdata [[
x y z
x y z
][
x y z
x y z
...
][
...
] def
it is an PostScript array of array. The Perl script MakeData.pl allows to plot a file of the 3D-data of a mathematical function z=f(x,y) and the Perl script PrepareData.pl prepares the data file into the above structure for using it with the example file.

contour1.png
The plain contour data of the function f(x,y)=sin(x)*sin(y).

contour2.png
The same as a 3D image.

(17MByte!) contourN.data (first example, 2MByte!) 3d.data (second example -- math function, 4MByte!)

you have to unzip the data file before using it!
