+\section{Contour plots}
+%--------------------------------------------------------------------------------------
+Contour plots are 2D-images but 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:
+\begin{verbatim}
+/contourdata [[
+x y z
+x y z
+][
+x y z
+...
+][
+...
+] def
+\end{verbatim}
+it is an PostScript array of array. The Perl script \url{http://tug.org/pstricks/pst-plot/3D/MakeData.pl}
+allows to plot a file of the 3D-data of a mathematical function $z=f(x,y)$ and the Perl script
+\url{http://tug.org/pstricks/pst-plot/3D/PrepareData.pl} prepares the data file
+into the above structure for using it with the example file.
+
+\begin{LTXexample}[pos=t]
+\psset{unit=1.75cm}
+\begin{pspicture}[showgrid](-3,-3)(3,3)
+\pstContour[colored]{contourN.data}
+\end{pspicture}
+\end{LTXexample}
+
+\emph{Important} is the option \verb|-dNOSAFER| for the \texttt{ps2pdf} run, otherwise Ghostscript
+didn't allow the run of external data files.
