how to adjust the distance between x ticks

[Li Xue]

Hello,

The labels of x ticks in my plot is too long and they overlapped. How can I make the distance between x ticks larger?

Thanks,

Li

Check out the breaks argument in scale_x_continuous, e.g.

qplot(1:10, 1:10)

qplot(1:10, 1:10) + scale_x_continuous(breaks = c(1,5,10))

Cheers

david.

Hey David,

Thank you for your prompt reply.

Is there anyway that I can still show all x-ticks and just make the interval between x-ticks larger?

Thanks a lot,

Li

You can enlarge the viewing window (either when you are viewing or saving, see ggsave() and enlarge the width).

Otherwise, if you are having a hard time reading them, say, if they overlap for example, you can try something like

labs <- paste('Sample text', 1:10)

qplot(factor(1:10), 1:10) + 

  scale_x_discrete(labels = labs) +

  opts(axis.text.x = 

    theme_text(angle = 30, size = 8, vjust = 2, hjust = .75))

Hope it helps

david.
