ordering with respect to stacking

[adam.l...@pnc.com]

Hi all,

Had a question about stacking if anyone has time.

Not sure if it's unique to factors with three levels, but was having difficulty arranging stacks in a bar plot in the order required.

The following example shows that changing the orders of the factor impacts the color pattern, but not the position of the levels in the stack. On the other hand, using the diamonds dataset, I was able to make the desired adjustment, so it's unclear to me what's unique about my example.

Here's the example showing how changing the order of factors changes the colours assigned to each level, but doesn't impact the position of levels in the stack (as desired and which is achievable with the diamonds dataset).  

        tst<-data.frame(y=c(1,1,1,2,2,2,3,3,3),x=c("a","a","a","b","b","b","c","c","c"),z=rep(c("x","y","z"),3))

        tst$z2<-factor(tst$z,levels=c("z","y","x"))

        ggplot(tst,aes(x,y))+geom_bar(stat="identity",aes(fill=z2),position="stack")
        ggplot(tst,aes(x,y))+geom_bar(stat="identity",aes(fill=z),position="stack")

Thanks very much for the help! Once again.

It's the stat="identity" that's screwing things up for you. Try

ggplot(tst,aes(x,y))+geom_bar(aes(fill=z2),position="stack")

which correctly puts z at the bottom of the stacks.
