如何旋转echarts4r雷达图上的轴标签？

Question

可重现的示例：

library(echarts4r)

# Sample data
data <- data.frame(
  Category = c("A", "B", "C", "D", "E"),
  Value = c(80, 50, 60, 70, 40)
)

# Creating a radar chart
e_charts(data, Category) |> 
  e_radar(Value)

我尝试在标签 A、B、...、E 中不旋转的情况下进行操作：

e_charts(data, Category) |> 
  e_radar(Value) |> 
  e_radar_opts(
    axisLabel = list(
      rotate = 45
    )
  )

Answer 1

您需要设置

nameRotate

对象的

indicator

属性。

library(echarts4r)

# Sample data
data <- data.frame(
  Category = c("A", "B", "C", "D", "E"),
  Value = c(80, 50, 60, 70, 40)
)

# Creating a radar chart
e_charts(data, Category) |> 
  e_radar(Value) |> 
  e_radar_opts(
    axisName = list(
      color = "blue",
      formatter = JS("function (value, indicator) {
                        indicator.nameRotate = 45;
                        return value;
                      }")
    )
  )
