My question is very similar in spirit to this question: What is the best plotting library for Python?

What is my best bet for plotting data in C? Am I better off forgoing a library and just generating data that I can feed directly into gnuplot?

My impetus for this question is being able to visualize DSP transformations while studying the excellent resources found in an earlier question of mine. So the focus is really just 2D plots, histograms, etc.; 3D isn't as important right now.

I think you are on the right track with gnuplot. For what you want, it's very powerful and flexible.

However, you may want to consider writing to gnuplot directly from your application instead of creating data and feeding it. There is an ANSI C API to gnuplot available.
