Hi Nick, Maybe two things off hand (booted into OS X right now where I can't try your code..)
1) try using straight gnuplot without going through org to verify your commands. This helps make sure that the syntax isn't producing errors. Another way to check this out sometimes is to C-c C-c on the code block, run the code, and then C-x b to the *gnuplot buffer to view any error messages. Those might prove helpful. 2) try changing your plot line to: plot data using 1:2:3 notitle I think I ran into an issue using "$data" even though it's the gnuplot syntax. I found org examples on the mailing list where just "data" was used instead (no quotes) and that worked. John P.S. Are you trying to make a 3D graph? plot using 1:2:3 will yield a 3D graph and you didn't mention a z-axis label so I'm wondering if that's really what you want? You may want to split this into two graphs to have date vs. time and date vs. distance? Or date vs. distance/time (speed)? P.P.S Or perhaps judging by the boxwidth option you want the width of the bars in the graph to represent the miles run? In that case you want 'plot data using 1:2:3 with boxes notitle' I think.
