修改通过ggplotly创建的图的工具提示信息 [英] Modify tooltip info of a plotly graph created via ggplotly

问题描述

运行了自己的聚类算法后，我有了这个数据集以及它们各自的x和y，我想要一种使用交互式视图对其进行分析的方法.

I have this dataset and their respective x and y after I ran my own clustering algorithm and I want a way to analyze it with an interactive view.

value max_value Var1 x y 3 6 potato 4 2 4 4 banana 3 2 5 6 apple 3 1

value max_value Var1 x y 3 6 potato 4 2 4 4 banana 3 2 5 6 apple 3 1

我正在尝试使用plotly，我想让plotly查看器仅向我显示相应点的工具提示/鼠标悬停信息上的值和max_value.这是我到目前为止的内容:

I'm trying to use plotly and I'd like to have the plotly viewer show me only the value and max_value on the tooltip/hoverinfo of the respective point. This is what I have so far:

gg <- ggplot(test) + 
  geom_point(aes(x = x,y =  y, color = Var1), size = 4, alpha = 0.5)
ggplotly(gg)

#alternative
plot_ly(df, x = ~x, y = ~y, color = ~Var1)

是否可以更改该图在工具提示或其他程序包中显示的值，这可以帮助我解决此问题?

Is there a way to change the values that the plot show on the tooltip or another package that could help me in this?

推荐答案

您可以添加text美学的一些工具提示信息:

You can add some tooltip info with the text aesthetic:

library(plotly)
gg <- ggplot(test) + 
  geom_point(aes(x = x, y = y, color = Var1, 
                 text = paste0("Value: ", value, "</br>Max: ", max_value)), 
             size = 4, alpha = 0.5)
ggplotly(gg)

如果只需要value和max_value:

gg <- ggplot(test) + 
  geom_point(aes(x = x, y = y, color = Var1, 
                 text = paste0("Value: ", value, "</br></br>Max: ", max_value)), 
             size = 4, alpha = 0.5)
ggplotly(gg, tooltip = "text")
