pyGraph: Animated, Easy Client for 1D Line Plots

pyGraph is a freely available, lightweight and easy to use visualization client for viewing 1D data files which started out as a python re-implementation of yGraph. It includes features for animation, zooming and saving to png.

pyGraph was developed by David Radice. The source code can be obtained from the Mercurial repository https://bitbucket.org/dradice/pygraph/. pyGraph relies on https://bitbucket.org/dradice/scidata/ to read in Cactus data files.

Using pyGraph

pyGraph can be used to view one or multiple 1D data files with the format 

"Time=0.0
0.0  0.0
0.2  0.04
0.4  0.16
0.6  0.36
0.8  0.64
1.0  1.0

"Time=1.0
0.0  0.0
0.2 -0.04
0.4 -0.16
0.6 -0.36
0.8 -0.64
1.0 -1.0

Such files can be created with the Cactus thorns CactusBase/IOASCII and CactusBase/IOBasic

Viewing files is as easy as typing 

ygraph <data filename> <data filename>

The are several options for customising aspects of and using ygraph, a manpage can be built from the source, or type pygraph --help for more information.

If you are using thorn CactusConnect/HTTPD you can setup your browser to automatically view any advertised ygraph files. Instructions on how to do this are provided in the WebServer-HOWTO.

Getting Hold of pyGraph

Binaries and source code for ygraph are all available from the pyGraph mercurial repository.
