Hi Eric, If I change your example org file a little by adding row and column names to the table as in the attached file I get the following behaviour that I don't understand: if I execute C-c on the shell function the file /tmp/data.gnuplot has the format that gnuplot can plot; however, if I execute C-c on the gnuplot function the form of /tmp/data.gnuplot is mangled with "" and () so it can no longer be plotted by the gnuplot command. Can you shed any light on this? Thanks, Paul
