Hello all,
I'm trying to make vertical density plots of the type found here: http://had.co.nz/ggplot2/stat_density.html (and see below for the clip). However, I'm trying to put two vertical bars side by side in each facet_grid category. So, for example, below I would like to have two vertical bars in the "Fair" category - one bar for one data group, and another bar for another. The same for "Good", "Very Good", etc.
Any ideas about how I might go about doing that?
Thanks!
Alex

?facet_wrap
ncol=2
ncol=2
might work

Hi:
Winston Chang developed geom_violin() to generalize this type of plot, so for your example below, this would work in versions of ggplot2 >= 0.9.0:
library('ggplot2')
library('scales')
ggplot(diamonds, aes(x = cut, y = price)) + geom_violin() # default
# variant
ggplot(diamonds, aes(x = cut, y = price)) + theme_bw() +
geom_violin(fill = "grey50") +
scale_y_continuous(labels = dollar)
Do you want separate sets of violin plots by a levels of a third (factor) variable or to superimpose dodged bar plots wrt a third variable on top of the violins? If the latter, what are the values that are supposed to represent the heights of the bars? A reproducible example apropos to your goals would be useful.
