Hi,
I'm trying to create a stacked bar plot using ggplot2. Rather than
plotting the count of each of the 13 "Bar" factors on the Y axis, I
would like to represent the sum of the Values associated with each of
the 13 "Bar" factors. Is there a way to do that? Given the following
data, that would obviously mean that there would be some negative sums
represented. Here's a bit of example data along with the command I've
been using.
>library(ggplot2)
> x
Value Bar Segment
1 1.10020075 1 1
2 -1.37734577 2 1
3 2.50702876 3 1
4 0.58737028 3 2
5 0.21106851 3 3
6 -2.50119261 4 1
7 1.34984831 5 1
8 -0.27556149 6 1
9 -1.54401647 6 2
10 -2.75975562 6 3
11 -0.09527123 6 4
12 1.36331646 7 1
13 -0.36051429 8 1
14 1.36790999 9 1
15 0.15064633 9 2
16 0.34022421 9 3
17 -0.64512970 10 1
18 0.83268199 11 1
19 -1.50117728 12 1
20 1.09004959 13 1
> qplot(factor(Bar), data = x, geom = "bar", fill = factor(Segment))
Thanks for any suggestions you might have.
James
