 Hello,
 Suggestion for shaded bars on time series plots, i.e. NBER recession .
 It would be quite nice if you could define shaded bars on a time series
 plot with a discrete variable. It could look something like
 gnuplot varlist --time-series --shading=dummy
 where dummy is a discrete variable and taking a value of 0 for all
 periods with no shading.
 Just a thought,
 
Yes it would be nice if that GUI feature could also be executed via 
script. (Or is it possible already?)
cheers,
sven
