geom_histogram and geom_blank: controlling y limits
I want to create a set of histograms that will make use of facet_wrap. The y limits vary a lot, sometimes there is no data for a given combination. So, I thought I could control the y limits using a dummy data frame and geom_blank.
Geom_blank() works as expected when I use geom_point() but not when when I use geom_histogram()
For example, I create these two data frames
test <- data.frame(grp=rep(c("a", "b"),3), x.value=rep(c(10,20,30), each=2),
y.value=rep(1:3, each=2))
dummy <- data.frame(grp=rep(c("a", "b"),3), x.value=rep(c(10,20,30), each=2),
y.value=c(0,10,10,20,20,30))
If I want to do a scatterplot:
p1 <- ggplot(test, aes(x=x.value, y=y.value)) + geom_point()
p1 <- p1 + facet_wrap(~grp, scales="free")
p1
p2 <- p1 + geom_blank(data=dummy)
p2
geom_blank() changed the y limits.
But when I try to create a histogram
p3 <- ggplot(test, aes(x=x.value, weight=y.value)) + geom_histogram(bins=6)
p3 <- p3 + facet_wrap(~grp, scales="free")
p3
p4 <- p3 + geom_blank(data=dummy)
p4
geom_blank() has no impact.
How can I control complex y limits on a set of histograms?

You need to map y.value to y like you did in p1 and p2.
p4 <- p3 + geom_blank(aes(y = y.value), data=dummy)
p4
