Legend Scroll issues.

[batra2]

I have a Shiny dashboard where I am rendering events on y axis. The scroll for the legend works fine when I render the UI for the first time.

But if I resize the UI or refresh the Page the scroll disappears.

Ok thanks for additional info. I think this makes more sense. I should be able to try to replicate Sunday.

This seems like a plotly.js problem. @timelyportfolio I know the plotly.js folks like reproducible example(s) using codepen, if possible.

Looking at this, I have not yet replicated it on just the JavaScript side (see codepen). I'll try to add some lines to see if that reproduces the issue. @batra2, if you can recreate with a minimal reproducible example, I would really appreciate it.

@batra2, I have been able to reproduce in R, so an example is no longer necessary. I'll let you know what I can find out.

@cpsievert, I replicated with the following code and noticed another sort-of-related problem. The legend scroll rect appears but has no impact in RStudio/Windows, but works as expected in Chrome and Firefox. Does the legend rect respond to drag in your RStudio?

#issue 525
#  Legend Scroll issues
#  issue states happens on resize with shiny
#  but I can replicate without shiny
#  as shown below

library(ggplot2)
library(plotly)
library(dplyr)

ggplotly(
  ggplot(
    mtcars%>%add_rownames(),
    aes(mpg,hp,color=rowname)
  ) +
    geom_point() +
    geom_smooth(
      aes(mpg,hp),
      inherit.aes=FALSE
    )
)

Everything works as expected for me in Chrome/Firefox, but I can't seem to click and drag the scroll bar in RStudio (mouse scroll is working, though).

[timelyportfolio]

Ok, same with me. Do you think I should file an issue on plotly.js or just accept that this is a limitation of RStudio Viewer (perhaps webkit) similar to #322?

I'll switch focus now back to the issue with legend scrolling on resize.

[timelyportfolio]

I think this gets fixed in v.1.7.0 (see plotly/plotly.js@7b393d4#diff-f48c57dae9095e916f13f364ae740f69).

[timelyportfolio]

Unfortunately, problem still there even though the scrolling legend behaves much better. I'll research a little more and file issue over on plotly.js.

This should now be fixed. Please reopen if you are still having trouble after updating to the newest version.
