what I'm asking is maybe best explained by example, see the script below, which calls R. Is something like that possible with gnuplot (and hence more directly linkable to gretl) ? <hansl> # The following produces a dynamic browser-based plot # with a slider at the bottom to choose the range open denmark foreign language=R --send-data library(dygraphs) # in turn depends on "magrittr" moneyincome <- cbind(gretldata[,"LRM"], gretldata[,"LRY"]) dygraph(moneyincome) %>% dyRangeSelector() end foreign </hansl>

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. Hehe, notice that I asked "possible with gnuplot", not "possible with gretl". The idea is of course to leverage and benefit from existing tools, and especially not to reinvent the wheel.
