Hi John, I would actually like to plot different lines per distance, each that correlate to a date and elapsed-time (x and y axis respectively). I get an error with the :file notation, though I read that in a sample babel gnuplot example for generating graphs of commit history on the org-mode git repository. I tried to reference the variable data without the quotes and $ sign without any success. I will continue to fiddle with it, I am new to gnuplot.
