r - 如何在漏斗图中具有固定大小但动态悬停文本？

Question

我正在尝试使用 R 制作漏斗图。

问题是数字存在偏差，并且没有统一的表示形式。然而，我们想展示流程。那么如何在 R 中制作漏斗图，其中漏斗的大小是固定的，但文本是动态的并且来自数据框列。

查看源代码示例: https://plot.ly/r/funnel-charts/

requiredPackages <- c("plotly")

ipak <- function(pkg){
  new.pkg <- pkg[!(pkg %in% installed.packages()[, "Package"])]
  if (length(new.pkg))
    install.packages(new.pkg, dependencies = TRUE)
  sapply(pkg, require, character.only = TRUE)
}

ipak(requiredPackages)

p <- plot_ly(
  type = "funnelarea",
  values = c(5, 4, 3, 2, 1),
  text = c("The 1st","The 2nd", "The 3rd", "The 4th", "The 5th"),
  marker = list(colors = c("deepskyblue", "lightsalmon", "tan", "teal", "silver"),
                line = list(color = c("wheat", "wheat", "blue", "wheat", "wheat"), 
  width = c(0, 1, 5, 0, 4))),
  textfont = list(family = "Old Standard TT, serif", size = 13, color = "black"),
  opacity = 0.65)

p

结果

Answer 1

_{我想显示如上所示的漏斗图；但悬停时我想显示不同的文本。隧道仅用于表示形状，但悬停将显示实际值。}

根据OP的上述评论，我猜测他们希望hoverinfo从这个值向量c(5,4,3,2,1)中选择其文本。

第一个图表/解决方案适用于此问题:

library(plotly)

plot_ly(
  type = "funnelarea",
  values = c(5, 4, 3, 2, 1),
  text = c("The 1st","The 2nd", "The 3rd", "The 4th", "The 5th"),
  marker = list(colors = c("deepskyblue", "lightsalmon", "tan", "teal", "silver"),
                line = list(color = c("wheat", "wheat", "blue", "wheat", "wheat"),
  width = c(0, 1, 5, 0, 4))),
  textfont = list(family = "Old Standard TT, serif", size = 13, color = "black"),
  opacity = 0.65,
  hovertemplate = '%{value}<extra></extra>')

It's possible to add more text/values. Below is an example of that. You can read more here: https://plot.ly/r/hover-text-and-formatting/

plot_ly(
  type = "funnelarea",
  values = c(5, 4, 3, 2, 1),
  text = c("The 1st","The 2nd", "The 3rd", "The 4th", "The 5th"),
  marker = list(colors = c("deepskyblue", "lightsalmon", "tan", "teal", "silver"),
                line = list(color = c("wheat", "wheat", "blue", "wheat", "wheat"), 
  width = c(0, 1, 5, 0, 4))),
  textfont = list(family = "Old Standard TT, serif", size = 13, color = "black"),
  opacity = 0.65,
  hovertemplate = paste('%{value}<extra></extra>' ,
                        '%{text}<extra></extra>'))
