Wrong scaling on ggplotly facet_wrap within shiny

[abbatidanilo]

Hello,

I met an issue on the plot result when using the ggplotly on ggplot with facet_wrap. This happens when there is a lot of antigens that is a lot of different plots to wrap together with facet_wrap

This is the code generating the wrong scaling plots:

p <- ggplot(ggdf, aes(x = expression, color = sample_id, group = sample_id)) +
    geom_freqpoly(stat = "density") + 
    facet_wrap(~ antigen, scales = "free", ncol = colonne, nrow = righe) +
    scale_color_manual(values = sample_color)
  
  p <- ggplotly(p = p, originalData = TRUE)

Here colonne = 2 and righe = 12 so we have 24 plots wrapped together.

The same problem happens (but less often) outside shiny implementation and with both originalData parameter setting (FALSE or TRUE)

As you can see below, only the first and the latest row are plotted correctly while all the plots in between are kind of compressed...

Hi, I highly doubt the problem has to do with plotly.js code here, so it would be best to open an issue over at https://github.com/ropensci/plotly/issues/new

Thank you!

Looks like you probably want to pass the size of the container to ggplotly(), like this:

Thank you very much Sievert,
now it works perfectly, but now I have a doubt concerning the whole UI process with the session$clientData. The first time I run the routine and I try to pass the session$clientData$output_pid_width into the ggplotly function I only have the session$clientData$$output_pid_hidden available (the session$clientData$output_pid_width and the session$clientData$output_pid_height are still NULL)
Is this normal (that is you have to output before to switch from hidden to active) or am I missing anything?
