Re: [ns] [bug] xgraph crashes when output is to a file

[Di-Fa Chang <difac@usc.edu>]

it also broke in my linux box (RedHat 7.1, kernel 2.4.2-2).
I'm tracing this bug. But you may try other ploting tools:
  Grace -   http://plasma-gate.weizmann.ac.il/Grace/
  Plplot -  http://plplot.sourceforge.net/
  R -       http://www.r-project.org/
