Create non-overlapping stacked area plot with ggplot2

Question

I have some data scraped and processed from the web in this form:

>head(dat)
  count  name          episode    percent
1   309   don 01-a-little-kiss 0.27         


        

Answer 1

That was interesting. You're missing a single row (Lane didn't appear in Tea Leaves...?), so

dat2 <- rbind(dat,data.frame(count = 0,name = 'lane',
                    episode = '02-tea-leaves',percent = 0))

ggplot(arrange(dat2,name,episode), aes(x = episode,y = percent)) + 
  geom_area(aes(fill=name,group = name), position='stack')

appears to work. But it had to be in the right order as well, and I'm not entirely sure why.
