如何在ggplot2的boxplot上显示观测的名称？

debugcn 发表于 Dev

假设您有一个包含公司名称，效率指标及其值的数据框。我想通过指标可视化值的分布。此外，我想在方框图中显示公司名称。

我成功制作了箱线图。但是，我也尝试使用geom_text(label = ...)显示公司名称。在我只想显示特定公司的名称之前，也可以。

问题：如何在箱形图中仅描绘一个公司名称？

样本数据：

我试图做的是：

ggplot(sampleData, aes(x = indicator, y = value)) +
  geom_boxplot() + geom_text(label = comp_name)

好吧，答案在表面上。

在这里找到：https : //www.r-graph-gallery.com/275-add-text-labels-with-ggplot2.html

如果要放置一个或多个标签，请根据需要使用geom_text或geom_label过滤数据框。像这样

    ggplot(data, aes(x = factor, y = value)) + 
       geom_boxplot() + 
       geom_label(data = data %>% filter(indicator == "f1"), aes(label = indicator))

您甚至可以制作自定义标签。
