ggplot to ggplotly does not accept variable alpha

[aljrico]

I'm trying to convert a ggplot that has alpha in its aesthetics (it needs to be variable), which works perfectly in ggplot, but ggplotly() outputs an error.

set.seed(666)
y <- rpois(1000, 2.9)
table(y)

holdThis <- as.data.frame(table(y))
holdThis$cumTotal <- cumsum(holdThis$Freq)
holdThis$percentage <- (as.numeric(holdThis$Freq)/10000) * 100
holdThis$y <- as.numeric(as.character(holdThis$y))

p <- ggplot(holdThis, aes(x=y, y=Freq, alpha = Freq)) + geom_bar(stat='identity', fill= 'blue', color="black", size = .25) + scale_x_discrete(breaks = y)

ggplotly(p)

same is true for geom_segment

Any chance you found a solution for this? I have been googling for a few days now with no apparent solution to the problem: It won't translete no matter what I do.

I also encountered this problem. My current work-around is setting the alpha value through the fill attribute but this does not always work well, so it would be so great if this issue could be fixed!

In the meantime, I believe that it would be really nice if the error message could be modified and point to this issue (to avoid people spending hours on it like myself).
