plotlyOutput height 100% does not work (width does)

[ambevill]

It is possible to pass width='100%' into plotlyOutput so that the plot takes all of the horizontal space. The help text also suggests height='100%' as an example, but this always results in a 400px static height.

However, plotly plots are usually 100% height and width when the graphs are stand-alone HTML, so I'm not sure why it wouldn't be possible to have 100% height within a Shiny app.

library(shiny)

ui = shinyUI(fluidPage(plotly::plotlyOutput('plot', width='100%', height='100%')))

server = shinyServer(function(input, output, session) {
  output$plot = plotly::renderPlotly({ plotly::plot_ly(data=airquality, x=~Ozone, y=~Solar.R) })
})

runApp(list(ui=ui, server=server))

The Shiny plotOutput doc mentions that "for height, using "auto" or "100%" generally will not work as expected, because of how height is computed with HTML/CSS". So maybe the plotlyOutput doc needs a similar statement (if auto height is not possible for technical reasons).
