<title>XGraph - an animating plotting program
<description><url>http://jean-luc.ncsa.uiuc.edu/People/Paul/xgraph.html</url>
XGraph with animation is a modification of the popular XGraph plotting
program written by David Harrison at UC Berkeley. The original
program supported line plots (and restricted surface plots) on any X11
display, and had several useful features, including being able to zoom
on a region with the mouse.

I (Paul Walker) added two features to the original code. First, it does
crude animation of data sets. The animation merely pages through data
sets in the order in which they are loaded. It is quite crude, but useful if
all your data sets are in one file in time order, and are output at uniform
times. Also, the code will take derivatives of your data numerically,
and display those derivatives in a new XGraph window.
