Question

我有一个csv文件，我将其缩小为3列并放置在数据框中。数据是该日期的日期，数字和十六进制颜色代码。我想制作一个水平的棒棒糖图表，并一直关注

*编辑以在代码部分添加示例数据

一切正常，直到我想通过调用颜色列设置分段颜色。然后，它失去了颜色的排序。

我不太了解mutate函数，因此我猜想它正在发生。如果有人可以解释那里发生的事情，那也将不胜感激。

library(tidyverse)
dir <- 'C:[file directory]'
setwd(dir)
file <- "KK3s.csv"
mydata <- read.csv(file, header=T, as.is=T)

#add color column with a baseline color
mydata$color <- rgb(249, 161, 26, maxColorValue=255)
#change color based on W or L 
mydata$color[mydata$W.L<"W"] = rgb(43, 81, 52, maxColorValue=255)

#Reduce df to only necessary columns
data <- data.frame(x=mydata$Match.Up, y=mydata$X3PM, WLcolor =  mydata$color)

data %>%
  arrange(y) %>%
  mutate(x=factor(x,x)) %>%
  ggplot( aes(x=x, y=y)) +
    geom_segment( aes(x=x, xend=x, y=0, yend=y),
