【问题描述】：

当我使用功能ggplotly（来自plotly包）时，如何更改弹出标签内容（删除附图中红色矩形中的标签内容）？

library(tidyverse)
library(plotly)
mdate <- c(44197,44198,44199,44200,44201,44202,44203,44204,44205,44206,44207,44208,44209,44210,44211,44212,44213,44214,44215,44216,44217,44218,44219,44220,44197,44198,44199,44200,44201,44202,44203,44204,44205,44206,44207,44208,44209,44210,44211,44212,44213,44214,44215,44216,44217,44218,44219,44220)
myear <- c(2021,2021,2021,2021,2021,2021,2021,2021,2021,2021,2021,2021,2021,2021,2021,2021,2021,2021,2021,2021,2021,2021,2021,2021,2020,2020,2020,2020,2020,2020,2020,2020,2020,2020,2020,2020,2020,2020,2020,2020,2020,2020,2020,2020,2020,2020,2020,2020)
amount <- c(45,2,2,87,93,32,31,42,84,93,24,13,12,48,39,33,88,78,15,6,51,55,32,93,14,16,11,84,47,87,40,45,57,76,24,91,11,96,44,82,99,17,75,59,22,89,61,93)

p <- data.frame(mdate,myear,amount) %>% 
  mutate(mdata=as.Date(mdate),
         myear=as.factor(myear)) %>% 
  ggplot(aes(x=as.Date(mdate),y=amount,color=myear))+geom_line()+
  theme_minimal()

ggplotly(p)

【问题讨论】：

是否要编辑默认工具提示？

@AnilGoyal 对，这就是我想要的。谢谢！

【参考方案1】：

我们可以将工具提示的规范（即要使用的值）传递给 plotly：

p <- data.frame(mdate,myear,amount) %>% 
  mutate(mdata=as.Date(mdate, origin ="1904-01-01"),
         myear=as.factor(myear)) %>% 
  ggplot(aes(x=mdata, y=amount, color=myear)) +
  geom_line()+
  theme_minimal() 

ggplotly(p, tooltip = c("y", "colour"))

附：虽然 ggplot2 确实允许拼写“颜色”和“颜色”，但情节似乎坚持“颜色”......

感谢您的帮助，太好了！

我遇到了一个额外的问题：有没有办法改变 ggplotly 工具提示的填充颜色和板颜色？你能帮忙吗，谢谢！
