echarts4r量程图值(%)

Question

我有一个最小的例子，希望以百分比显示值。有什么想法吗？

在这里你可以找到API文档。

maxValue <- 160

echarts4r::e_charts() %>% 
  echarts4r::e_gauge(
    value = round(runif(1, 0, maxValue)), 
    name = "description",
    radius = "80%",
    startAngle = 210, #225,
    endAngle = -30, #-45,
    min = 0,
    max = maxValue,
    splitNumber = maxValue/20
  )

抱歉，我刚碰到这件事。

这个能行吗？计算百分比R-侧，并使用formatter添加百分比符号.

maxValue <- 160

echarts4r::e_charts() %>% 
  echarts4r::e_gauge(
    value = round((runif(1, 0, maxValue) / maxValue) * 100), 
    name = "description",
    radius = "80%",
    startAngle = 210, #225,
    endAngle = -30, #-45,
    min = 0,
    max = maxValue,
    splitNumber = maxValue/20,
    detail = list(
      formatter = "{value}%"
    )
  )
