在R Plotly工具提示中使用自定义文本无法显示%{text}值

发布于11月01日

我正在try 使用text = 和%{text}在Ploly栏中显示myvar1个值，并将其作为工具提示文本的一部分.然而，我的代码不能充分地生成工具提示，并且显示"%{Text}"而不是它的相应值(如下图所示).

以下是我的代码:

library(plotly)
dfcom <- data.frame(
  myvar1 = c("Media", "Campaigns", "Website"),
  alcance = c(6814511L, 400000L, 225329L),
  type = c("viewers", "viewers", "viewers"))
plot_ly(
  dfcom,
  x = ~alcance, y = ~type,
  text = ~myvar1,
  textfont = list(color = I("white")),
  type = 'bar',
  color = ~myvar1,
  colors = c("chartreuse4", "darkolivegreen", "darkgreen"),
  showlegend = FALSE,
  hovertemplate = "%{x:,.0f} people reached by %{text} <extra></extra>") %>%
  layout(barmode = "stack")

推荐答案

我不确定为什么%{text}或%{hovertext}失败了(here它在工作)，但是%{customdata}似乎工作了:

library(plotly)
dfcom <- data.frame(
  myvar1 = c("Media", "Campaigns", "Website"),
  alcance = c(6814511L, 400000L, 225329L),
  type = c("viewers", "viewers", "viewers")
)
plot_ly(
  data = dfcom,
  x = ~ alcance,
  y = ~ type,
  text = ~ myvar1,
  # hovertext = ~ myvar1,
  customdata = ~ myvar1,
  textfont = list(color = I("white")),
  type = 'bar',
  color = ~ myvar1,
  colors = c("chartreuse4", "darkolivegreen", "darkgreen"),
  showlegend = FALSE,
  hovertemplate = "%{x:,.0f} people reached by %{customdata}<extra></extra>"
) %>%
  layout(barmode = "stack")
