如何用R语言的Highcharts库将饼图转换为环形图？

只需在hc_add_series()中添加innerSize参数，即可将饼图转换为环形图。该参数用于设置饼图中心空白区域的尺寸，通常以百分比为单位。

修改后的完整代码 #

highchart() %>% 
  hc_add_series(type = "pie", data = age, hcaes(Age, Mean_percentage_viewed), 
                size = "60%", innerSize = "40%", # 新增innerSize定义环形内半径
                name = "Mean Percentage viewed", center = c(50, 50), 
                dataLabels = list(distance = -50, 
                                  formatter = JS("function () {
                                                  return this.y > 5 ? this.point.name : null;
  }"))) %>% 
  hc_title(text = "Age group share")

参数说明 #

• innerSize = "40%"：控制环形中心空白区域的大小，数值越小环形越宽，数值越大环形越窄，可根据视觉需求调整百分比。
• 其余参数保持原有设置即可，数据标签、标题等交互功能不受影响。

你提供的数据集 #

age <- structure(list(Age = c("13–17 years", "18–24 years", "25–34 years", 
"35–44 years", "45–54 years", "55–64 years"), Views = c(0.38, 
70.01, 20.2, 6.91, 2.37, 0.13), Mean_view_duration = c("0:01:51", 
"0:02:25", "0:02:42", "0:02:58", "0:02:57", "0:02:23"), Mean_percentage_viewed = c(21.71, 
21.23, 24.31, 26.36, 24.94, 19.27), Watch.Time.Hours = c(0.28, 
67.14, 21.58, 8.11, 2.76, 0.12)), class = "data.frame", row.names = c(NA, 
-6L))
