I can never remember how to rotate the x-axis labels with ggplot2: theme(axis.text.x = element_text(angle = 90, hjust = 1, vjust = 0.5))
# Adapted from https://stackoverflow.com/a/7267364/1036500 by Andrie de Vries
# This is it: theme(axis.text.x = element_text(angle = 90, hjust = 1, vjust = 0.5))
library(ggplot2)
td <- expand.grid(
hjust=c(0, 0.5, 1),
vjust=c(0, 0.5, 1),
angle=c(0, 45, 90),
text="text"
)
td$angle_exp <-
with(td,
ifelse(angle == 0, "angle = 0",
ifelse(angle == 45, "angle = 45",
"angle = 90")))
,
ggplot(td, aes(x=hjust,
y=vjust)) +
geom_point(colour = "red",
size = 5) +
geom_text(aes(label=text,
angle=angle,
hjust=hjust,
vjust=vjust),
size = 5) +
facet_grid(~angle_exp) +
scale_x_continuous(breaks=c(0, 0.5, 1),
expand=c(0, 0.2)) +
scale_y_continuous(breaks=c(0, 0.5, 1),
expand=c(0, 0.2)) +
theme_minimal(base_size = 18) +
ggtitle("To rotate x-axis label text 90 degrees we use:\ntheme(axis.text.x = element_text(angle = 90, hjust = 1, vjust = 0.5))")

I look this up on Google, maybe once a week ;-), thanks for the help!

I think it's because the names are not so intuitive. ( I also in the group, can't remember it, I can try to by heart it) :P

There is an alternative since 3.3.0: stackoverflow

guides(x=guide_axis(angle = 90))

the h/v-just are set automatically sensibly
