Question

我有一个使用plotly和ggplot2的代码。当我将信息悬停时，内部信息会重复，这意味着它会为所有图形显示2条相同的TrendName信息行。例如，这是它在悬停信息中显示的内容

Month_Names：2011-05 Actual_volume：56488 TrendName：2010-11 - 2017-01 TrendName：2010-11 - 2017-01

如何仅显示1个TrendName？谢谢

这是我的代码

library(ggplot2)
library(dplyr)
library(tidyr)
library(plotly)

Month_Names <- c("2010-11","2010-12",
             "2011-01","2011-02","2011-03","2011-04","2011-05","2011-06","2011-07","2011-08","2011-09","2011-10","2011-11","2011-12",

构建aes对象时，ggplot中有4个变量。当您使用ggplotly时，它将使用工具提示中的所有映射美学。

要删除由group和color引起的重复，您需要在工具提示中指定要用作字符向量的项目。（注意拼写颜色，您也可以使用group）。

ggplotly(p, tooltip = c("x","y","colour")) %>% 
  layout(title = "New plot title", 
         legend = list(orientation = "h",x = 0.25, y = -.75)
  )

使用ggplot2绘制重复的悬停信息
