I am trying to graph the following data:
to_graph <- structure(list(Teacher = c("BS", "BS", "FA"
), Level = structure(c(2L, 1L, 1L), .Label = c("BE", "AE", "ME",
"EE"), class = "factor"), Count = c(2L, 25L, 28L)), .Names = c("Teacher",
"Level", "Count"), row.names = c(NA, 3L), class = "data.frame")
and want to add labels in the middle of each piece of the bars that are the percentage for that piece. Based on this post, I came up with:
ggplot(data=to_graph, aes(x=Teacher, y=Count, fill=Level), ordered=TRUE) +
geom_bar(aes(fill = Level), position = 'fill') +
opts(axis.text.x=theme_text(angle=45)) +
scale_y_continuous("",formatter="percent") +
opts(title = "Score Distribution") +
scale_fill_manual(values = c("#FF0000", "#FFFF00","#00CC00", "#0000FF")) +
geom_text(aes(label = Count), size = 3, hjust = 0.5, vjust = 3, position = "stack")
But it
- Doesn't have any effect on the graph
- Probably doesn't display the percentage if it did (although I'm not entirely sure of this point)
Any help is greatly appreciated. Thanks!
