geom_label() in plotly

[lindsayrutter]

Thank you for such a useful and user-friendly package!

I recently tried to use plotly for a ggplot2 object that had geom_label(). I received a warning message that geom_label() has yet to be implemented in plotly, and to post an example code here for any geom that may be useful to be implemented.

library(ggplot2)
library(plotly)

dat=data.frame(label=paste0("label",seq(1:5)), xstart = seq(10,50, by=10), ystart = seq(1:5)+.1, xend = c(seq(20,50, by=10), 50), yend = c(seq(1:4)+.9, 5.1), x = seq(10,50, by=10), y=seq(1:5))

myPlot = ggplot2::ggplot(data = dat,ggplot2::aes(x = x, y = y, label=label)) +
  ggplot2::geom_segment(ggplot2::aes(x=xstart, y=ystart, xend=xend, yend=yend)) +
  ggplot2::geom_label(fill = "grey80", size = 3) +
  ggplot2::scale_x_continuous(expand = c(.1, .1))

ggplotly(myPlot, tooltip = c("x", "label"))

The static myPlot object itself has five labels, labeled as "label1", "label2", "label3", "label4", and "label5" with x values of 10, 20, 30, 40, and 50. I was aiming for the last line to allow the interactive tooltip to show the label and x values for each of the five labels. Instead, it seems, upon running the last line, that the geom_labels disappear, and upon hovering over, the interactivity is on the values at the corners of the edges from the geom_segment().

I just wanted to post it here in case it is of something of interest to the developers or others. Thank you!

adding support for geom_label (the duplicate page is locked)

I find geom_label very convenient in ggplot and would find it just as useful if it were available in ggplotly, as it makes geom_hline and geom_vlines easily labelable/readable, with nice text balloons and masking.
