[SOLVED] R plotly custom visualization margin padding

Good morning, 

I have finally managed to get rid of the extra padding introduced in the visualization. I appears the bug is with htmlWidgets, that introduces padding into the html file.

A simple R function can get rid of the padding, such as the one below:

ReadFullFileReplaceString <- function(fnameIn, fnameOut, sourceString,targetString) {
  if(!file.exists(fnameIn))
    return(NULL)
  tx  <- readLines(fnameIn,encoding = "UTF-8")
  tx2  <- gsub(pattern = sourceString, replace = targetString, x = tx)
  writeLines(tx2, con = fnameOut)
}

The calling the function like so:

ReadFullFileReplaceString('out.html', 'out.html', ',"padding":[0-9]*,', ',"padding":0,')

Credit goes to MS, as the solution was found in one of their R visualizations, PowerBI-visuals-forcasting-exp

in their script.r file: https://github.com/microsoft/PowerBI-visuals-forcasting-exp/blob/master/script.r
