Research direction

Start by reproducing the provided R example through ggplotly(p), comparing its handling of Inf and -Inf with ggplot2. Trace the plotting and range calculation path involved in that entry point; done means the values reach the plot limits without affecting ranges, zooming, axis labels, or grid lines.

Written by the indexing model from the issue text.

Description

plotly does not seem to know what to do with values that are Inf or -Inf. The expected behavior (as done by ggplot2) is to map those values to the maximum and minimum values representable in the type when plotting but to not include them in calculations related to ranges, zooming, axis labels, grid lines, etc.

library(dplyr)
library(ggplot2)
# as expected, this extends the line up to limits of the plot
p <- data.frame(x=c(1,1,Inf), y = c(Inf, 1, 1)) %>% ggplot(aes(x=x,y=y)) + geom_line()
p
library(plotly)
# This doesn't plot anything
ggplotly(p)
