如何在 ggplot 2 上的多面框 plot 中创建图例？

Question

我如何摆脱所有重叠的 x 轴标签，而是创建一个图例并按颜色过滤？

library(ggplot2)
#Load in the dataset
broadband = read.csv("broadbanddata.csv")
#Box plot 
ggplot(broadband) + geom_boxplot(aes(x = rsp, y = All.hour.trimmed.mean.latency)) +
  labs(title="Figure 1: Average internet speed", x="Type of technology", y="Average Latency in a Day")+
  facet_wrap(~technology)

Answer 1

尝试这个：

   library(ggplot2)
#Load in the dataset
broadband = read.csv("broadbanddata.csv")
#Box plot 
ggplot(broadband) + geom_boxplot(aes(x = rsp, 
                                     y = All.hour.trimmed.mean.latency, 
                                     fill = rsp)) +
        labs(title="Figure 1: Average internet speed",
             x="Type of technology",
             y="Average Latency in a Day",
             fill = "Average Latency in a Day")+
        theme(axis.text.x = element_blank())+
        facet_wrap(~technology)
