what I'm asking is maybe best explained by example, see the script

hence more directly linkable to gretl) ?

open denmark
foreign language=R --send-data
library(dygraphs) # in turn depends on "magrittr"
moneyincome <- cbind(gretldata[,"LRM"], gretldata[,"LRY"])
dygraph(moneyincome) %>% dyRangeSelector()

Gretl is coded in C, which is Turing complete, and its GUI is based on
GTK, which includes a slider widget (GtkScale), so the answer is Yes,
it's possible. All you have to do is design a GUI dialog that revises
the sample range in a gnuplot script via a call to the GtkScale API
and calls for redrawing of the plot accordingly.
