geom_text and font fuzziness

[Johannes Graumann]

Hi again,

If I do this:

> library(ggplot2)
> p <- ggplot(mtcars, aes(factor(cyl), mpg))
> p + geom_boxplot() + geom_text(aes(x=1,y=min(mtcars[["mpg"]]),label="TEST"))

The font of "TEST" comes out all fuzzy (tried X11 and postscript
devices).

How might that be fixable?

Thanks, Joh

Hi,

Your geom_text layer is using the default data.set, therefore it
superimposes many times the same label.

Try this instead,

library(ggplot2)
p <- ggplot(mtcars, aes(factor(cyl), mpg))
p + geom_boxplot() +

geom_text(data=data.frame(x=1,y=min(mtcars[["mpg"]])),aes(x=x,y=y,label="TEST"))

## or more concisely

library(ggplot2)
p <- ggplot(mtcars, aes(factor(cyl), mpg))

p + geom_boxplot() + annotate("text",x=1,y=min(mtcars[["mpg"]]),label="TEST")

HTH,

baptiste

(Late) Thanks for your hints! Kept struggeling with it until I figured out that
when starting q plot with "qplot" even your advice fails and one has to return
to a "ggplot"-based assembly.

Thanks, Joh
