I am trying to create a graphic graph for a brilliant application. I am facing a problem with some faceted chart layouts. Whenever there are four faces and they are in a 2x2 grid, the lower left side does not display any data, even though the data is in the ggplot figure. This also happens when there are 6 faces in a 3x2 grid and the bottom left falls again. The examples on the plotly ggplot page show several examples with a 2x2 grid and data displayed. I am not sure what the problem is. Any help is much appreciated.
Code:
library(ggplot2) library(dplyr) library(plotly) data %>% filter(!is.na(result)) %>% ggplot(aes(date_time, result)) + facet_wrap(~group, scales = "free_y") + geom_point() + geom_line() ggplotly()
ggplot output: 
ggplotly output: 
Data:
