drawing graphs in ubuntu

Question

I have a C code that collects data and places them in a 2-D array. I would like to plot this data on an xy graph (mathematics) automatically ie pass the data as parameters in a command line and get a graph

Are there any suggestions for how to do so?

Answer 1

gnuplot is a good one to look at assume you mean xy charts, if you want actual graphs then look at dot

Answer 2

gnuplot will do what you need. If you want to process the data before, you might want to try octave , which aims to be a matlab equivalen (still uses gnuplot as a frontend for graphing).

If you want even more control, you could write a script in python and use matplotlib .
