ggplot2: theme(axis.text=element_text(size=3) does not change font size on the y-axis-CodePudding

Using this code

FigureS8 <- plot(nonParametricBoot, "edge", plot = "difference", onlyNonZero = TRUE, order = "sample")

returns a figure where text labels on x- and y-axis are too big.

I therefore added theme():

FigureS8 <- plot(nonParametricBoot, "edge", plot = "difference", onlyNonZero = TRUE, order = "sample")
FigureS8   theme(axis.text=element_text(size=3))

Now font size on labels on the x-axis becomes smaller (as I want), but there are no changes to the fontsize on the y-axis. How can I change the font size on both?

CodePudding user response：

It might be an instance of this problem: ggplot2 theme: axis.text not inheriting from text?

Your theme needs to be 'complete' in order for axis.text.y to inherit from axis.text correctly. So either define a complete theme or just define both axis.text.x and axis.text.y

CodePudding user response：

Because you haven't specified which axis you want to change in you code, the axis.text is interpreted as applying only to the x axis, as that is always the first axis to be dealt with.

Therefore code should be:

  theme(axis.text.x = element_text(size = 3),
        axis.text.y = element_text(size = 3))
