Nvd3 controls issue

[jarmo-kauko]

Fixes #392, including following issues with nvd3 plots with controls

1. Adding controls creates html with indent, which pandoc interprets as preformatted code block.
2. <div id='...' class='rChart'> is generated twice: once by template$chartDiv and once from lib/controls/script.html.
3. Having multiple charts with controls doesn't work, as all angular controllers have the same name (DemoCtrl).

Thanks for the pull request. I am a little behind on some reorganization of code in the repo. Once I am done with that I will take a closer look at your pull request and merge the changes.

Hi, I still have the same problem with the controllers when I try to embed the plot in an html file. It works fine in the R-studio viewer, though. Any update since?

You can try with this code example

  '''{r results = 'asis', comment = NA}

  require(rCharts)
  require(datasets)

   p2 <- nPlot(mpg ~ cyl, group = 'wt', 
        data = mtcars, type = 'scatterChart')

   p2$xAxis(axisLabel = 'Log2')
   p2$yAxis(axisLabel = 'Log2')
   p2$chart(tooltipContent = "#! function(key, x, y, e){ 
        return  '<b>Name:</b>  ' + e.point.GeneID
      } !#")
   p2$chart(color = c('red', 'green'))
   p2$addControls("x", value = 'mpg', values = names(mtcars))
   p2$addControls("y", value = 'cyl', values = names(mtcars))
   p2$print('chart2', include_assets = TRUE)
   '''
