Label size in directlabels geom_dl()
Put cex
inside a list. Other formatting features should also be placed in the list. See some of the examples in ?directlabels::geom_dl
library(ggplot2)
library(directlabels)
dat = data.frame(x = 1:10, y = 1:10, z = letters[1:10])
ggplot(dat, aes(x, y)) +
geom_point() +
geom_dl(aes(label = z), method = list(cex = 2, rot = -45, hjust = -.5))
EDIT
The method too is placed in the list:
ggplot(dat, aes(x, y)) +
geom_point() +
geom_dl(aes(label = z), method = list("smart.grid", cex = 2))

I have really enjoyed the package
directlabels
for dynamic positioning the lables of a plot. Although still not perfect, it helps reasonably to prevent overlaps between labels of a scatter plots with many points for example - specially for the draft version of the charts, not the final one.However I can not find anyway to change the label size while using
geom_dl()
function. Is there anyway?I have tried to pass
size
andcex
as a normal oraes()
argument to the function.-

Ali over 11 yearsThanks, when I try to add geom_dl( aes(label = z), method="smart.grid", list(cex = 1, rot = -45, hjust = -.5)), It says: Error: ggplot2 doesn't know how to deal with data of class list. Would you please resolve it?

Sandy Muspratt over 11 years@AliSharifi,
"smart.grid"
too goes into the list:geom_dl(aes(label = z), list("smart.grid", cex = 2))

JohannesNE over 2 yearsWhy does
hjust
work when passed directly togeom_dl
, whilecex
doesn't?
