Could you provide a simple example? It seems you have something like

# t1 t2 t3
1 2 3
4 5 7
etc.

Do you intend to add columns 1+2 row-wise? If so:

plot 'data' using ($1+$2) title 'cols 1+2', '' using 3 title 'col 3'

I don't understand what you want to do here, since the stacked cols 1
and 2 will have twice the number of entries as column 3. An example
could clarify.

Probably with some combination of gnuplot and awk or perl.
