使用带有计数和百分比的 Plotly 在 R 中打开饼图/圆环图 [英] Open Pie Chart/Donut Chart in R using Plotly with count and percentage

问题描述

我正在尝试使用 plotly 在 R 中制作圆环图.我尝试了 ggplot，但它无法给我所需的效果.这是一个示例数据集:

库(dplyr)测试文件 <- tibble(personID = 1:10,status = c("bad", "good", "bad", "bad", "bad", "bad", "bad", "bad", "bad", "good"),Department = c("sales", "sales", "marketing", "sales", "marketing", "management", "management", "sales", "sales", "sales"))

此图表最终会出现在 PowerPoint 中，因此不需要响应.相反，我需要饼图在不滚动它的情况下说出落入每个状态的百分比和计数.此外，在饼图的中心，我希望它表示好"类别中的百分比.

这是我到目前为止的代码.它具有无需滚动即可看到的百分比，但没有计数，并且中心没有百分比.

图书馆(情节)p<-测试文件%>%group_by(状态)%>%总结(计数 = n())%>%plot_ly(labels = ~status, values = ~count) %>%add_pie(hole = 0.6) %>%布局(标题=好坏比例"，showlegend = F，xaxis = 列表(showgrid = FALSE，zeroline = FALSE，showticklabels = TRUE)，yaxis = list(showgrid = FALSE，zeroline = FALSE，showticklabels = TRUE))

此外，如果您能展示如何按部门对它进行 facet_wrap，那将非常有帮助.我一直让它说 NULL！

谢谢！

解决方案

如果您想在饼图/甜甜圈图的中心添加一个文本，您可以添加一个

库(dplyr)图书馆(情节)测试文件 <- tibble(personID = 1:10,status = c("bad", "good", "bad", "bad", "bad", "bad", "bad", "bad", "bad", "good"),Department = c("sales", "sales", "marketing", "sales", "marketing", "management", "management", "sales", "sales", "sales"))值 <- 测试文件 %>%group_by(状态)%>%总结(计数 = n())good <- values %>% filter(status == 'good')p <- plot_ly(values, label = ~status, values = ~count, text = ~count) %>%add_pie(hole = 0.6) %>%布局(标题=好坏比例"，showlegend = F，xaxis = 列表(showgrid = FALSE，zeroline = FALSE，showticklabels = TRUE)，yaxis = list(showgrid = FALSE，zeroline = FALSE，showticklabels = TRUE))p <- layout(p, annotations=list(text=paste(good$count/sum(values$count) * 100, "%", sep=""), "showarrow"=F))p

I'm trying to make a donut chart in R using plotly. I tried ggplot, but it wasn't able to give me the effect that I need. Here's a sample dataset:

library(dplyr)
testfile <- tibble(personID = 1:10,
                   status = c("bad", "good", "bad", "bad", "bad", "bad", "bad", "bad", "bad", "good"),
                   department = c("sales", "sales", "marketing", "sales", "marketing", "management", "management", "sales", "sales", "sales"))

This chart will end up in a PowerPoint, so it does not need to be responsive. Instead, I need the pie chart to say, without scrolling over it, the % that falls into each status and the count. Also, in the center of the pie chart, I want it to say the % that are in the "good" category.

This is the code that I have so far. It has the percentage visible without scrolling but not the count and it does not have the percentage in the center.

library(plotly)
p <- testfile %>%
  group_by(status) %>%
  summarize(count = n()) %>%
  plot_ly(labels = ~status, values = ~count) %>%
  add_pie(hole = 0.6) %>%
  layout(title = "Ratio of Good to Bad",  showlegend = F,
         xaxis = list(showgrid = FALSE, zeroline = FALSE, showticklabels = TRUE),
         yaxis = list(showgrid = FALSE, zeroline = FALSE, showticklabels = TRUE))

Also, if you could show how to facet_wrap it by department, that would be very helpful. I keep getting it to say NULL!

Thank you!

If you want to have a text in the center of your pie/donut chart you can add an annotation.

values <- testfile %>%
  group_by(status) %>%
  summarize(count = n())

good <- values %>% filter(status == 'good')

p <- layout(p, annotations=list(text=paste(good$count / sum(values$count) * 100, "%", sep=""), "showarrow"=F))

In order to change the label which is shown in each segment of your pie chart, you can use text.

p <- plot_ly(values, labels = ~status, values = ~count, text = ~count)

Complete code

library(dplyr)
library(plotly)

testfile <- tibble(personID = 1:10,
                   status = c("bad", "good", "bad", "bad", "bad", "bad", "bad", "bad", "bad", "good"),
                   department = c("sales", "sales", "marketing", "sales", "marketing", "management", "management", "sales", "sales", "sales"))

values <- testfile %>%
  group_by(status) %>%
  summarize(count = n())

good <- values %>% filter(status == 'good')

p <- plot_ly(values, labels = ~status, values = ~count, text = ~count) %>%
  add_pie(hole = 0.6) %>%
  layout(title = "Ratio of Good to Bad",  showlegend = F, 
         xaxis = list(showgrid = FALSE, zeroline = FALSE, showticklabels = TRUE),
         yaxis = list(showgrid = FALSE, zeroline = FALSE, showticklabels = TRUE))

p <- layout(p, annotations=list(text=paste(good$count / sum(values$count) * 100, "%", sep=""), "showarrow"=F))
p
