R help - Dec 2008 - diagonal lines in legends of ggplot2

Hi, I have the following problem with ggplot2: When I specify black contours
for bars in a barplot, ggplot automatically shows diagonal lines in the
legend boxes. Is there a way, to remove these diagonal lines?

 

Here's a simple example:

library(ggplot2)

df<-data.frame(x=gl(6,1),y=rnorm(6,100,50))

ggplot(df,aes(y=y,x=x,fill=x))+geom_bar(aes(group=x),colour='black',size=1)+
scale_fill_brewer(palette='Greys')

 

 

Thanks for your help!

Hi Erich,

Can you explain why you don't want them?  The philosophy behind the
legend code is to attempt to match the appearance of the geoms in the
plot as closely as possible.  There are a few exceptions, like this
diagonal line, where the legends are slightly different to make it
easier to see certain features of the geom (in this case edge colour
and size)

Regards,

Hadley
