[Gnuplot-info] perl and gnuplot

[Gary P. <web...@ar...>]

I am attempting to write a perl script to allow users to plot functions using
gnuplot through a web page.  It seems to work fine unless the function has any
additions in it. For example, "x+1" plots as just "x" and "x**2+x" won't plot at
all, in fact nothing with "+x" will plot.  

The apache error log has not been helpful to me.  I can post it if anyone thinks
it will help here.

I have tried running gnuplot in both batch and interactive modes.

A version of the script is availalbe at

Any suggestions would be greatly appreciated.
