Greetings.

I have been having an issue recently where the x-axis labels have been disappearing from graphs I've created in R once uploaded using api_create(). I've repeated this numerous times, and it seems entirely reproducible. I've supplied the short R code that highlights the issue. This x-axis disappearance occurs whether or not the ggplotly() function is called before api_create().

I've attempted to specify x-axis markers in ggplotly() as well before uploading, but these are stripped during upload. I've also removed all theme values, and the x-axis is still removed. I've changed the geom between bar() and col() to the same effect.

Here is the graph as intended:

Here is the graph after upload:

Code Example

example <- ggplot(mtcars, aes(x = rownames(mtcars), y = mpg)) + 
  geom_col() + 
  #geom_bar(stat = "identity") +  #X-Axis disappears in both geom_col() and geom_bar()
  ggtitle("Cars by MPG") + 
  ylab("Miles per Gallon") + 
  xlab("Car Make and Model") 

example.plotly <- ggplotly(example)
api_create(example.plotly, "Example/example")
