在 ggplot2中旋转和限制轴标签

Question

我有一个图，x 轴是一个标签很长的因子。虽然可能不是一个理想的可视化，但是现在我想简单地将这些标签旋转为垂直的。 已经用下面的代码解决了这个问题，但是正如你看到的，标签并不是完全可见的。

data(diamonds)
diamonds$cut <- paste("Super Dee-Duper",as.character(diamonds$cut))
q <- qplot(cut,carat,data=diamonds,geom="boxplot")
q + opts(axis.text.x=theme_text(angle=-90))

Answer 1

Change the last line to

q + theme(axis.text.x = element_text(angle = 90, hjust = 1))

By default, the axes are aligned at the center of the text, even when rotated. When you rotate +/- 90 degrees, you usually want it to be aligned at the edge instead:
