layout(hovermode = "x unified")Plotly 提供了通过添加或显示可移动的水平或垂直“尖峰线”的选项layout(hovermode = "y unified")（请参阅文档）。例如：

library(plotly)

x <- seq(from = 0, to = 2*pi, length = 100)
y <- sin(x)
fig <- plot_ly(x = x, y = y, type = "scatter", mode = "markers")
fig <- fig %>% layout(hovermode = "x unified")
fig

使用跟随光标的垂直线创建此图：

我想同时显示垂直和水平尖峰线。像这样：

我尝试像这样修改布局：

fig <- fig %>% layout(hovermode = "x unified") %>% layout(hovermode = "y unified")
# or
fig <- fig %>% layout(hovermode = c("x unified", "y unified"))
# …
