I know this is a very basic question, but I have trouble changing font size of axis labels in ggplot2. I used the code like below:
a <- ggplot(data1, aes(x=data2, y=data3)) +
geom_hline(yintercept=c(1, -1)) +
labs(x = data2, y = data3) +
theme_bw() +
theme(axis.text=element_text(size=10))
I tried to change the axis label size but they do not change.... Does anybody have suggestion?
axis.title
, notaxis.text
(which controls the individual value labels along the axis). – Marius
