R highcharter图点颜色基于值

Question

我是 highcharts 和 R highcharter 的新手。我有一个这样的数据框

tmp <- data.frame(x = 1:5, y = rnorm(5), color = c("green", "red", "green", "orange", "red"))
# x       y  color
# 1  0.4421  green
# 2 -0.8924    red
# 3  0.8264  green
# 4  0.6695 orange
# 5 -0.0966    red

我想用highcharter画。

对于点的颜色，我想让点的颜色成为数据框中对应的颜色。

我该怎么办？即使它是 R 代码，任何 JS 解决方案都会很感激，因为我可以用 R 重写它。

Answer 1

如果您以十六进制格式提供颜色变量，highcharter 将识别这些颜色

tmp <- data.frame(x = 1:5, y = rnorm(5), color = c("#00FF00", "#FF0000", "#00FF00", "#ffa500", "#FF0000"))

hchart(tmp, "line", hcaes(x, y, color = color))

Answer 2

稍微改进的解决方案：

set.seed(1)
tmp <- data.frame(x = 1:5, y = rnorm(5), 
          color = c("green", "red", "green", "orange", "red"))
dummy <- "two"

library(highcharter)
hchart(tmp, type="scatter", hcaes(x=x, y=y, color=color), 
       marker=list(symbol='circle', radius=5), zIndex=1) %>% 
  hc_add_series(tmp, type="line", color="lightblue", zIndex=0)
