Thanks, Sven. I will try the code you've provided in the
console.
Upon further digging, I found the following on stackoverflow re gnuplot:
https://stackoverflow.com/questions/50338019/gnuplot-histogram-chart-with...
Can the code on that stackoverflow page somehow be mapped into something the gnuplot
under the hood of gretl will understand?
Is this close to what you need?
<hansl>
function void multi_hist(list L)
n = nelem(L)
vn = varnames(L)
mh = ""
outfile --buffer=mh
printf "set style fill solid 0.5\n"
printf "set style data histogram \n"
printf "set style histogram clustered\n"
strings names = array(n)
loop foreach i L
names[i] = "hist" ~ "$i"
freq $i --quiet --silent
f = $result
cnameset(f, "")
printf "$%s << EOD\n", names[i]
printf "%12.4f", f
printf "EOD\n\n"
endloop
printf "plot "
loop i = 1 .. n
printf "$%s using 2 t \"%s\"", names[i], vn[i]
if i == n
printf "\n"
else
printf ", "
endif
endloop
end outfile
gnuplot --inbuf=mh --output=display
end function
### example
open mroz87.gdt
list L = HE WE
multi_hist(L)
