Nice :-)

at the moment we support column based calculations only and our parser for=
 the
formulas doesn't have any support for row/cell accesses.

We need to add this in near future. Until then you'll need to calculate th=
e
values outside of LabPlot and copy the values into the spreadsheet or
calculate them in a CAS-worksheet inside of LabPlot with octave or pyhon, =
etc.
and plot the results in LabPlot. Some examples for this approach were give=
n in
https://labplot.kde.org/2016/07/23/labplot-2-3-0-released/.

Best Regards,
Alexander
