Open source graphing / plotting library?

sysop · 06-05-2007, 12:21 PM

I'm trying to find a C library I can use that can create line graphs given some specific arguments like height / width / array of co-ordinates.

Does anybody know of any graphing libraries that I can use?

I don't know about a library API for it, but I find gnuplot tough to beat for versatility and performance. I've used it embedded into applications by piping data into it, and having it save plot files on disk.
Are you looking to produce presentation style (hardcopy-friendly), web style graphics, other...?
Depending on your exact requirements, it might be easy enough to roll your own package.

You want a library, huh? I googled this:

Code:

graphing library

and about the sixth non-sponsored entry was this pointer:

Code:

theNbomr's suggestion of gnuplot is good for expanding your horizons, and the caltech link might be just what you're looking for.
