Start by running the three reproductions in the issue. Compare the trace that ggplotly() builds for geom_point against geom_line when the text aesthetic varies, for example by inspecting plotly_build() output. The fault is probably in how the line trace's hover text is converted, not in the plot itself. Done when a geom_line with a per-point tooltip renders its line and the tooltip still works.

描述
Hello,
I have stumbled across a very strange little bug, if I try to make a custom tooltip on a plot converted from ggplot2 with ggplotly, then it works fine with geom_point but breaks (nothing is plotted) with geom_line. But, only when the text of the tooltip varies with the data.
For example, here we have everything working as expected with geom_point:
library(plotly)
p <- mtcars |>
mutate(
text = paste0("test: ", row.names(mtcars))
) |>
ggplot(aes(x = disp, y = mpg, text = text)) +
geom_point()
ggplotly(p, tooltip = "text")
However, if I now use geom_line instead, the data disappears even though it must be there as the tooltip works:
library(plotly)
p <- mtcars |>
mutate(
text = paste0("test: ", row.names(mtcars))
) |>
ggplot(aes(x = disp, y = mpg, text = text)) +
geom_line()
ggplotly(p, tooltip = "text")
But, if I change the tooltip text back so that it's a constant string (i.e. doesn't change with the data) then everything plots fine, again.
library(plotly)
p <- mtcars |>
mutate(
text = paste0("test: ", "constant")
) |>
ggplot(aes(x = disp, y = mpg, text = text)) +
geom_line()
ggplotly(p, tooltip = "text")
What's even weirder is that the plotting will work fine with a varying tooltip, but only when it's the default tooltip:
library(plotly)
p <- mtcars |>
mutate(
text = paste0("test: ", "constant")
) |>
ggplot(aes(x = disp, y = mpg)) +
geom_line()
ggplotly(p)
