在 echarts4r `e_pie` 饼图中显示计数和百分比

Question

我想在 e_pie 从 echarts4r 创建的圆环图中绘制计数 and/or 百分比。

这是文档的link。

以下是文档中的示例，生成了以下没有计数和百分比的圆环图：

mtcars %>% 
  head() %>% 
  dplyr::mutate(model = row.names(.)) %>% 
  e_charts(model) %>% 
  e_pie(carb, radius = c("50%", "70%")) %>% 
  e_title("Donut chart")

我正在寻找的是从 R plotly 中实现的这样的东西：

mtcars %>% 
  head() %>% 
  dplyr::mutate(model = row.names(.)) %>% 
  plot_ly(labels = ~ model,
                    values = ~ carb,
                    textinfo = 'value+percent',
                    marker = list(colors = c("#ABDDDE","#F8AFA8"),
                                  line = list(color = '#000000',
                                              width = 0.75)
                                  )
          ) %>%
    add_pie(hole = 0.6) %>%
    layout(title = " Donut chart", showlegend = T)

Answer 1

您可以使用 e_labels 定义标签，并使用 e_title 和 e_legend 对齐文本：

mtcars %>% 
  head() %>% 
  dplyr::mutate(model = row.names(.)) %>% 
  e_charts(model) %>% 
  e_pie(carb, radius = c("50%", "70%"))  %>% 
  e_title("Donut chart",
          textAlign  = "center",
          left ="50%") %>%
  e_labels(show = TRUE,
           formatter = "{c} \n {d}%",
           position = "inside") %>%
  e_legend(right = 0, 
           orient = "vertical")

在文档中，格式化程序 {c} 和 {d} 列为

{c}: the value of a data item.
{d}: the percent.
