r - 如何从 ggplot 中的箱线图中删除图例？

问题描述

请在My Data下面找到。

如何从箱形图中删除红色的圆圈图例？

在此处输入图像描述

我希望保持相同的颜色和设计。我尝试了许多不同的解决方案，但不幸的是，这并没有解决问题。

这可能有点基本，但根本无法弄清楚如何解决这个问题。我希望你能提供帮助 - 在此先感谢！

我的脚本是：

df <- data.frame(x = as.factor(c(p$WHO.Grade)),
                 y = c(p$ki67pro),
                 f = rep(c("Ki67pro"), c(nrow(p))))



ggplot(df) +
  geom_boxplot(aes(x, y, fill = f, colour = f), outlier.alpha = 0, position = position_dodge(width = 0.78)) +
  scale_x_discrete(name = "", label=c("WHO-I\nn=108","WHO-II\nn=34","WHO-III\nn=1")) +
  scale_y_continuous(name="Ki-67 proliferative index", breaks=seq(0,30,5), limits=c(0,30)) +
  stat_boxplot(aes(x, y, colour = f), geom = "errorbar", width = 0.3,position = position_dodge(0.7753)) +
  geom_point(aes(x, y, fill = f, colour = f), size = 3, shape = 21, position = position_jitterdodge()) +
  scale_fill_manual(values = c("#52C1C76D"), name = "",
                    labels = c("\nTotal cohort\nn=159\n ")) +
  scale_colour_manual(values = c("#51BFC4"), name = "",
                      labels = c("\nTotal cohort\nn=159\n "))

解决方案

您可以使用theme()如下：

... + theme(legend.position = "none")

这应该消除传说
