Which version and how should I install snip snap to have graph available? Thanks, claudio pacchiega claudio.pacchiega@primeur.com 2004-03-12 17:51:38.441 2004-03-12 17:51:38.107 comment-SnipGraph Life-3 The graph macro you see here is available in the current CVS tree. If you have a ~~graph-snipsnap.jar~~ in your lib directory of snipsnap or packaed in the war file you can use the graph macro. Make sure the snipsnap server is started with "-Djava.awt.headless=true" or it may fail due to a missing graphics environment. Except for the psp style all other kinds should work. 2004-03-12 18:18:41.185 2004-03-12 18:18:40.868 comment-SnipGraph Life-4 I get the following exception.

If I take character by character the example, I get __graph: null__ as a result.
