[R] How two have two legends on a chart with different groups?
I'm trying to have two legends on a chart, with two sets of data with subgroups. Currently ggplot is are merging the to sets of data together. I would like to have the vertical lines in there own legend and not affect the colour shading or show up in the "type" legend. How would I go about doing this? df <- data.frame(val1=rnorm(300, 75, 10), val2=rnorm(300, 75, 10),type=rep(c("A", "B", "C"),100)) cuts1 <- data.frame(Stats="Stat A", vals=c(43, 70, 90)) cuts2 <- data.frame(Stats="Stat B", vals=cuts2 <- c(46, 79, 86)) cuts <- rbind(cuts1,cuts2) ggplot(df, aes(x=val1, y=val2, group=type)) + geom_line(aes(colour=type))+ geom_point(aes(colour=type))+ geom_vline(data=cuts, aes(xintercept=vals, linetype=Stats, colour = Stats), show_guide = TRUE) I got the idea of how to do this from: Add vline to existing plot and have it appear in ggplot2 legend? -- View this message in context: http://r.789695.n4.nabble.com/How-two-have-two-legends-on-a-chart-with-different-groups-tp4688666.html Sent from the R help mailing list archive at Nabble.com.
