ggplot2：没有标签的刻度标记的刻度线较短 [英] ggplot2: Have shorter tick marks for tick marks without labels

问题描述

我有一个使用ggplot2的情节，我想在x轴上有许多刻度，但是只有一些刻度会有与它们相关的刻度标签。但是，我希望那些有标签的刻度线比那些没有标签的刻度线更长。

I have a plot using ggplot2 in which I'd like many ticks along the x-axis, yet only some of the ticks will have tick labels associated with them. However, I'd like the tick marks for those that have labels to be longer than those that don't.

推荐答案

你可以通过初始 plot 调用（使用 xaxt ='n'）来抑制x轴，然后使用 tcl 来控制标记长度（参见？par ）和两个轴（1 ，...）调用。

In base R, you can suppress the x-axis with the initial plot call (with xaxt='n'), and then use tcl to control tick length (see ?par) with two axis(1, ...) calls.

plot(1:10, xaxt='n', ylab='', las=1)
axis(1, at=1:10, tcl=-0.8)
axis(1, at=seq(0, 11, 0.2), labels=NA)
