I am trying to overlay two sets of data that with be used in bar charts. The first is the main set of data and I want that to be the main focus. For the second dataset I want just a line marking where on the chart it would be. I can get close to what I want by doing this:
Tbl = data.frame(Factor = c("a","b","c","d"),
Percent = c(43,77,37,55))
Tbl2 = data.frame(Factor = c("a","b","c","d"),
Percent = c(58,68,47,63))
ggplot(aes(x = Factor, y = Percent), data = Tbl)
geom_bar(position = "stack", stat = "identity", fill = "blue")
ylim(0,100)
geom_bar(aes(x = Factor, y = Percent), data = Tbl2,
position = "stack", stat = "identity", fill = NA, color = "black")
theme_bw()
