[Gretl-users] [gnuplot] passing variables as arguments

Hello there, I'd like to produce a bunch of customised graphs with gretl in a loop, where I fix the axis ranges depending on values that I calculated beforehand. A minimum (not-) working example is below. ------- nulldata 240 series aa = normal(0,2) series bb = 2^normal(0,2) series cc = 3^normal(0,2) scalar minx = min(bb)<min(cc)?min(bb):min(cc) scalar maxx = max(bb)>max(cc)?max(bb):max(cc) gnuplot aa bb --output="bb.png" { set xrange[$minx:$maxx]; } gnuplot aa cc --output="cc.png" { set xrange[$minx:$maxx]; } ------ This does not work because one cannot pass $minx Is there another way to do so?
