I'm a bit experienced with GNUPlot but completely new to pyxplot. I'm trying to make a plot of a data file and the value that I wanted plotted is the difference between the value in the row i minus the value in row i-1. I know that using $ you can perform operation with values from different columns but I don't know how to do it for different rows.
Thanks in advance! :)

Did you ever work out a way to do this? I need to get the value of the last item in a column :/
