文本参数未正确传递到 plotly 条形图中的 hovertemplate [英] Text argument is not passed correctly to hovertemplate in plotly bar chart

问题描述

我使用自定义悬停模板创建了下面的条形图，但是当我将鼠标悬停在条形上方时，我得到的是 "text" 而不是我的 text.

I create the barchart below with a custom hovertemplate but instead of my text I get a "text" when I hover over the bars.

Cum4c<-structure(list(Country = c("United States Of America", "Mexico", 
                                  "United Kingdom", "Brazil", "Germany"), Deaths = c(91765, 31887, 
                                                                                     31134, 29081, 22546), lab = c("91,765", "31,887", "31,134", "29,081", 
                                                                                                                   "22,546")), row.names = c(NA, -5L), class = c("tbl_df", "tbl", 
                                                                                                                                                                 "data.frame"))
    
    fig1 <- plot_ly()%>%
      add_bars(data = Cum4c, x = ~Country, y = ~Deaths,
               text = ~ paste("<b>Country:</b>", Country, "<br><b>Deaths:</b>", lab),
               hovertemplate  = paste('%{text}<extra></extra>'),
               colors = c("#60ab3d","#6bbabf","#c4d436","#3e5b84","#028c75"),
               color = ~Country
               
               
               
      ) 
    fig1 <- fig1 %>% layout(showlegend = TRUE,title=list(text="worldwide,by selected territories and period",x = 0,y=1,font=list(size=10)),
                            font = list(color = '#a2a2a2'),
                            legend=list(y=1.2,x=0,title=list(text='<b> Top 5 </b>')),
                            
                            yaxis = list(fixedrange = TRUE,title="",
                                         #dtick = 250000

推荐答案

有两种方法可以达到您想要的结果:

There are two approaches to achieve your desired result:

1. 去掉 text 并改为使用 hovertemplate = ~paste("Country:</b>", Country, "<br><b>死亡:</b>>"，实验室)

去掉 hovertemplate 并使用 hoverinfo = 'text' 代替.

Get rid of hovertemplate and use hoverinfo = 'text' instead.

两种方法都会给你相同的结果.

Both approaches will give you the same result.

library(plotly)

fig1 <- plot_ly() %>%
  add_bars(
    data = Cum4c, x = ~Country, y = ~Deaths,
    hovertemplate = ~paste("<b>Country:</b>", Country, "<br><b>Deaths:</b>", lab),
    colors = c("#60ab3d", "#6bbabf", "#c4d436", "#3e5b84", "#028c75"),
    color = ~Country
  )
fig1

fig1 <- plot_ly() %>%
  add_bars(
    data = Cum4c, x = ~Country, y = ~Deaths,
    text = ~ paste("<b>Country:</b>", Country, "<br><b>Deaths:</b>", lab),
    hoverinfo = 'text',
    
    colors = c("#60ab3d", "#6bbabf", "#c4d436", "#3e5b84", "#028c75"),
    color = ~Country
  )
fig1
