Salutations
I have a simple script that plots different columns and blocks using the
looping capabilities in gnuplot4.6 (and many thanks to those who coded
it up).
in the loop I have
plot 'myfile' using rfchan index dut with lines {etc etc}
where rfchan and dut are for loop variables.
This works perfectly other than I realize now it would be better scaled
in mA rather than A. Were I using just column 2 (say), it would be easy
plot '' using ($2*1000) {etc etc}
but (rfchan*1000) will resolve to looking for column (rfchan*1000).
Is there an easy way to do both the computed column and value multiply ?
TIA
Pete

I´d say you want to use
plot for [i=1:10] "" using(column(i)*1000)
, if i understood you problem correctly.

You understood it correctly and that works perfectly
Many thanks
