array variables?

[<pl...@pi...>]

Hi,

I have to plot some data that depend on a parameter (pump speed) that I 
read in with each line of data. I need to calculate a plot value 
dependant on this value. I had it parametised as a function I call form 
the plot command but this is not accurate enough. I need it to be a 
look-up table (ie array) of values.

flo(dac)=flo_grad*(dac-16)+flo_0;

this needs to be

flo(dac)=speed[n];

I know use of variables is somewhat limited in gnuplot and I can't find 
any documentation that seems relevant. (array keyword referring to input 
format)

I have 16 values so a whole stack of 'if's would be pretty messy.

now am I missing a trick or is this simply not possible with the kind of 
algebra available within a gnuplot script?


best regards. Peter.
