highcharter名义价值和百分比价值 [英] highcharter both nominal and percentage values

问题描述

我用高轮图书馆制作了一张饼图。
$ b

I've made a pie chart with the highcharter library.

library(highcharter)

test_data
  Gender  Freq  colors
1 Female 29813 #ff99cc
2   Male 38474 #2980b9

hchart(test_data, "pie", hcaes(x = Gender, y = Freq, color=colors))

由于地图是交互式的，因此我希望饼图在同一图上显示百分比值和名义值 / strong>即可。

As the map is interactive, I want to have the pie chart showing both percentage values and nominal values on the same plot.

我有什么想法可以做到这一点？

Any ideas how I can do this?

推荐答案

您需要在工具提示选项中使用具有highcharter的JS（）函数的格式化程序。此外，Highchart使用'this.point.percentage'来提供百分比。请确保不要在第一行末尾忘记％>％。

You need to use a formatter with JS() function of highcharter, in the tooltip options. Moreover Highchart uses the 'this.point.percentage' to provide the percentages. Make sure not to forget the %>% at the end of the first line.

诀窍：

This should do the trick for you:

hchart(test_data, "pie", hcaes(x = Gender, label=Gender,y = Freq, color=colors))%>%

hc_tooltip（formatter = JS （）：{+ this.y +'，百分比：'+ Highcharts.numberFormat（this。通过添加该行（再次使用magrittr''），使用HTML = FALSE）

％>％'是在行之前或之后）：
hc_plotOptions（pie = list（dataLabels = list（enabled = TRUE，format ={point.label}：{point.y }）））

by adding the line (again the magrittr '%>%' is needed before or after the line): hc_plotOptions(pie =list(dataLabels = list(enabled = TRUE,format="{point.label}:{point.y}")))

您可以在标签上添加值或通过交换 {point.y} 与：

you can add on the labels the values or by exchanging the {point.y} with the:

{point.percentage：.2f}％，您可以添加百分比和标签（男，Felame）

{point.percentage:.2f}%, you can add the percentage along with the label (Male,Felame)
