[R] ggplot2 histogramm

[ONKELINX, Thierry]

I think you need 
	scale_fill_continuous("Your new label")

Note that you can simplify 
	scale_y_continuous(formatter = "percent") + ylab("Anteil in %") 
To
	scale_y_continuous("Anteil in %", formatter = "percent") 

HTH,

Thierry

To call in the statistician after the experiment is done may be no more
than asking him to perform a post-mortem examination: he may be able to
say what the experiment died of.

The plural of anecdote is not data.

The combination of some data and an aching desire for an answer does not
ensure that a reasonable answer can be extracted from a given body of
data.

Hi,

i get no success change the title of the "fill" (colour) legend and the
defintion of "levels". Have anybody a hint how i can do this.

df <-
data.frame(variable=sample(c("A","B","C"),1000,replace=T,prob=c(0.22,0.2
8,0.5)),group=gl(2,500))
p <- ggplot(df, aes(x = variable))
p + geom_histogram(aes(y= ..count.. /
sum(..count..),fill=..count../sum(..count..)*100))  +
scale_y_continuous(formatter = "percent") + facet_wrap(~group)  +
ylab("Anteil in %") +  xlab("Attribute") +
opts(title="Title",legend.text="Anteil in Prozent") +
BaseTheme(base_size=12)

many thanks,
Christian
