将鼠标悬停在 Plotly 图上时，有没有办法添加更多信息？

Question

我做了一个图表，你可以在下面看到。将鼠标悬停在 Plotly 图表上时，您可以看到图表中存在的有用信息，例如 Store Num 等。有没有办法添加到此标签，所以当有人悬停时他们也可以看到 branding ？如，不只是 Store Num？谢谢！

Store Num	mean_sales	mean_outreach	branding
1	200	1200	1
2	4200	1403	2

plotly::ggplotly(ggplot(data, aes(x= mean_sales, y= mean_outreach, label= `Store Num`))+
                   geom_point() +geom_text(aes(label= `Store Num`),hjust=20, vjust=20) +
                   ggtitle("Examining Marketing Campaign Outreach"))

当我尝试写两个标签时，标签本身会发生变化，但 Store Num 和 branding 的值都是商店编号。因为我想要的两个标签都没有正确显示。

plotly::ggplotly(ggplot(data, aes(x= mean_sales, y= mean_outreach, label= `Store Num`))+
                   geom_point() +geom_text(aes(label= branding),hjust=20, vjust=20) +
                   ggtitle("Examining Marketing Campaign Outreach"))

Answer 1

您可以通过 text 美学（参见 https://plotly-r.com/controlling-tooltips.html#tooltip-text-ggplotly）的自定义工具提示实现您想要的结果：

library(plotly)

ggplot(data, aes(
  x = mean_sales, y = mean_outreach, label = Store.Num,
  text = paste0(
    "mean_sales: ", mean_sales, "<br>",
    "mean_outreach: ", mean_outreach, "<br>",
    "Store Num: ", Store.Num, "<br>",
    "branding: ", branding
  )
)) +
  geom_point() +
  geom_text(hjust = 0, vjust = 0) +
  ggtitle("Examining Marketing Campaign Outreach")

ggplotly(tooltip = "text")

或者，如果您只想将信息添加到默认值，您可以这样做：

ggplot(data, aes(
  x = mean_sales, y = mean_outreach, label = Store.Num,
  text = paste0(
    "branding: ", branding
  )
)) +
  geom_point() +
  geom_text(hjust = 0, vjust = 0) +
  ggtitle("Examining Marketing Campaign Outreach")

ggplotly(tooltip = "all")

将鼠标悬停在 Plotly 图上时，有没有办法添加更多信息？

Is there a way to add more information when hovering over a Plotly graph?
