通过三种颜色将直方图分为低值区，中值区和高值区。

数据准备

# 加载数据
data <- data.table::fread(jsonlite::read_json("https://hiplot.cn/ui/basic/tricolor-histogram/data.json")$exampleData$textarea[[1]])
data <- as.data.frame(data)

# 整理数据格式
data$draw_color <- ifelse(data$value < 5, "#F44336",
                          ifelse(data$value > 7, "#006064", "#3F51B5")
)

# 查看数据
head(data)
    values draw_color

2 4.354496    #F44336
3 5.569931    #3F51B5

可视化

# 三色直方图
p <- ggplot(data, aes(x = values, fill = draw_color)) +
  geom_histogram(alpha = 0.5, binwidth = 0.05, position = "identity") +
    scale_fill_manual(values = c("#3F51B5", "#006064", "#F44336")) +
  theme_bw()
