在plotly散点图中设置hoverinfo文本 [英] Set hoverinfo text in plotly scatterplot

问题描述

我用下面的图创建了一个基本的散点图.问题是，虽然我专门在hoverinfo中设置了文本，但数值却要多显示一次-(20,56)-在要显示的实际文本-Team Pts:20 Fantasy Pts: 56之前.如何删除它们?

I create a basic scatterplot with plotly like the one below. The issue is that while I set specifically the text inside the hoverinfo the numeric values are displayed one more time- (20,56) -before the actual text- Team Pts:20 Fantasy Pts: 56 -that I wish to display. How can I delete them?

pts<-c(10,20,30)
npts<-c(24,56,78)
ex<-data.frame(pts,npts)


library(plotly)
p <- plot_ly(data = ex, x = ~pts, y = ~npts,
             marker = list(size = 10,
                           color = 'white',
                           line = list(color = 'rgba(152, 0, 0, .8)',
                                       width = 2))) %>%
  add_trace(
    text = ~paste("Team Pts: ", pts, '</br>Fantasy Pts:', npts),
    hoverInfo='text'
  )
p

推荐答案

一种方法是通过在hovertemplate参数中添加变量，将文本添加到每个数据点.

One way of doing this is to add the text to each data point, by adding in a variable to the hovertemplate parameter.

我目前无法测试此方法，但它看起来应该像这样:

I don't have a way to test this at the moment, but it should look something like this:

add_trace(
           x = ~pts,
           y = ~npts,
           hovertemplate = paste('<i>Team points</i>: %{x}',
                                '<br><b>Fantasy Pts</b>: %{y}</br>',
                                 )
      )
