Hi All

I have a simple quick question: does anyone have any recommendations on a graphing with C? I've done some graphing in the past with Python using Matplotlib and rather than re-invent the wheel I was hoping that someone might be able to point me in the right direction for graphing header files.

Please don't read this as a request for an explanation or tutorial, but if anyone knows of a good way to achieve this I'd be greatful. I'm really just looking for a starting point for futher investigation.

Ideally I'd like to produce graphs (line graphs in particular, but having the option for pie, bar and area graphs would also be useful) in a PNG or JPEG format.

I've heard that MATLAB is good from what I've Googled, but if anyone has some experience with Graphing with C I'd love to hear the "good bad and ugly" :)

Thanks for reading this post!

Wow! Just looked at MATLAB and the license is £1550! If anyone knows of a open source alternative they can recommend that would be great!

Thanks,

I've just found "FreeMat" which is an open source alternative to MATLAB. Has anyone else used this with C code?

Thanks

I have had situations where I needed to graph a complex mathematical model for some application, such as compression, encryption, image, and number theory analysis. I honestly didn't think there were programs out there that do this kind of thing. What I would do instead was just make a GUI application in C to plot the specific nature of my analysis which takes some time to develop but in the end its quite flexible and powerful. Either way this software you mentioned intrigues me.
