I found gnuplot_i first but this is way simpler :) By the way if you want to plot data from your c-program, first tell gnuplot to read it from stdin: fprintf(pipe, "plot '-'\n"); Then print all the data you want (probably in a loop) fprintf(pipe, "%lf %lf\n", variable1, variable2); ... When you're done tell gnuplot that data ends here fprintf(pipe, "e\n"); Thanks, just what I was looking for. I found gnuplot_i first but this is way simpler :)
By the way if you want to plot data from your c-program, first tell gnuplot to read it from stdin:
fprintf(pipe, “plot ‘-’\n”);
Then print all the data you want (probably in a loop)
fprintf(pipe, “%lf %lf\n”, variable1, variable2);
…
When you’re done tell gnuplot that data ends here
fprintf(pipe, “e\n”);

Try to install it using macports or fink. Check their website and the documentation to see how to use them. It means that you don’t have gnuplot installed or maybe is not in your PATH.

I get the error: sh: gnuplot: command not found Can anyone help me! Thanks I tried ypur code in an Xcode project I’m working on.

I get the error:

sh: gnuplot: command not found

Can anyone help me!

Thanks

I am generating random numbers and calculating their averages... I need the averages to be plotted on the graph but i dont want to save the averages to a file.

I want to use gnuplot for both plotting and fitting in my code, and I want to read gnuplot's output. Is it possible to do? Thanks, Dan Hi,

I have found it to be very good for publication-quality 2D graphics (it doesn't do 3D). I like the Pylab/Matplotlib package:
