Hi, Michael Gnuplot has a simple way of outputing to files: prepare the plot you want, tune it to your liking, and when you're ready use the 'set terminal' and 'set output' command. Basically, the terminal command tells gnuplot the format of the output (png, jpeg, ps, etc), and the output tells it where you want it. A simple example: (... lines to prepare plot ...) set terminal png set output "mygraph.png" replot That replot line simply redraws your last plot... but now it draws to the new terminal. When you want to draw back to X windows, set your terminal to 'x11' or 'wxt' (your default terminal is shown right above the prompt when you invoke gnuplot). Any tutorial that teaches you how to plot is good, once you know how to output the plot the way you want to. On Mon, 2011-05-23 at 15:41 -0700, Michael Litchard wrote:
I've looked for a tutorial for using the Haskell gnuplot wrapper, and can't find anything. If you can think of one off the top of your head, please let me know. I'd like to see how to use it to generate 2D and 3D histograms expressed in a png (or any) file. As far as I can see, the examples that come with gnuplot don't generate files.
