add offset to multiple columns in gnuplot -


i trying plot multiple column file first column x , rest should y columns this:

plot for[col=2:36:1] 'datafile' using 1:col lines lc rgb 'black' notitle

this works fine want offset y columns constant value.

i tried this:

plot for[col=2:36:1] 'datafile' using 1:(col-const) lines lc rgb 'black' notitle

but doesn't work (it seems plot difference between variable col , constant value const).

is there way this? have found here how offset y column 2 column file (or specific column in file)

plot 'otherdatafile' using 1:($2-const) lines

but can expanded case?

thanks in advance,

lucian

using 1:(column(col)-const) should work
