I'm not exactly clear on the request, but perhaps this will help clarify. Need to extract the desired portion of the ddf object to give to the geom_area function: ggplot(data=ddf,aes(x=x,y=y)) + geom_line(color="blue") + geom_area(data=ddf[(5<ddf$x)&(ddf$x<7.5),], inherit.aes=FALSE, aes(x=x,y=y,fill=fill) ) -- David. > > > Windows 10 > > R version 3.6.1 > > > > All best wishes > > Troels Ring > > Aalborg, Denmark > > > [[alternative HTML version deleted]] > > ______________________________________________ > R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide http://www.R-project.org/posting-guide.html > and provide commented, minimal, self-contained, reproducible code.
