Gnuplot is very useful tool to plot graphs and other related things.
There are plently of tutorials and how-tos everywhere.
One issue i faced while generating png images was changing fonts.
I wanted to change the font type to "vera" and increase the size.
First check if this font is installed.
$yum install bitstream-vera-font
Search for where it is installed
$rpm -ql bitstream-vera-font
/usr/share/fonts/bitstream-vera
$export GDFONTPATH=/usr/share/fonts/bitstream-vera
Now in either on the gnuplot terminal or your script file just add this.
set terminal png truecolor nocrop enhanced font Vera 20
