\chapter{Sample plots and QDP files}
\label{samples}

This appendix contains several sample figures that were created
with the QDP program.
In all the figures, the name of the QDP file used to generate the
figure is displayed in the top left corner.
For the first figure this name is {\tt XANADU:[PLOT.QDP]SPIRAL.QDP}.
It is possible to reproduce this figure by using:
\begin{verbatim}
$ QDP XANADU:[PLOT.QDP]SPIRAL
\end{verbatim}

For reader convenience, the top section of each QDP file is listed.
In cases where the QDP also uses a PLT command file, the top section
of the {\tt .PCO} file is also listed.
A careful comparison of each figure and the PLT commands used to
generate it, will illustrate the actions of many PLT commands.
