If you are talking about scripting graphs, then Gnuplot is what you
need - it's in the core centos distro I think.
If you want a dedicated gui graphing application, then you can't go far
wrong with Grace - it's in EPEL. I've used it for producing publication
quality plots but it's equally capable of dealing with everyday
graphing. The native save file format is simple and plain text, so it's
quite easy to generate the files using a script which can then be read
straight in to grace and will have correct axes, lables, etc.
another tool i've used for creating various sorts of graphs is Gnu
Octave. this is a matlab replacement, and if you can import a bunch of
numbers, you can graph them 8 ways from sideways.
