Welcome to the PSTricks web site Contour plots |

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 ... ][ ... ] defit 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. The plain contour data of the function f(x,y)=sin(x)*sin(y). The same as a 3D image. (17MByte!) contourN.data (first example, 2MByte!) 3d.data (second example -- math function, 4MByte!)
