I need to do the following because I am using mod_perl and I do not want to write then read from a temp file:
1. My script pipes info to gnuplot beta 3.6.
2. Gnuplot reads config info from standard in, creates plot in GIF format and outputs it on standard out.
3. My script captures gnuplot output to a varaible.
4. My script outputs varaible to web page.
I tried IPC::Open2 but could not capture all the output.
