How would one enable a theme for highcharts? If we include it in the asset pipeline then it gets loaded in before Highcharts.js and thus will not work.

Can you please update it to the latest version (which is 3.0.9)?

highcharts-rails gem has a Highcharts module, whereas in this gem it is a class. Is it possible to make them play nicely? Perhaps by creating a class Highcharts::Chart as I did in my library which I started, which does likewise with this one.

I was struggling a lot to try and display plotLines on graphs and having a ton of trouble. I eventually figured it out, but I think it could be a systemic problem with Array based options. A documentation of my problem and solution can be found at http://stackoverflow.com/questions/13281657/using-highcharts-with-rails-not-displaying-plotlines

I tried the following...

chart.plotOptions(series: {stacking: 'percent'})

which of course doesn't work, since I note that there is no built-in way to handle stacking, so I tried the following:

class Highcharts
class PlotOptions
class PlotType < Base

  def initialize(opts = {})
    @suboptions = {
      :dataLabels => 'Labels',
      :dial => 'Base',
      :events => 'PlotOptions::PlotType::Events',
      :marker => 'PlotOptions::PlotType::Marker',
      :pivot => 'Base',
      :point => 'Point',
      :states => 'PlotOptions::PlotType::States',
      :stacking => 'Base'
    }
    super
  end

end

end
end

Of course Base wants a Hash.

I also tried creating a custom class and setting the class constant string above to 'Stacking':

class Highcharts
class Stacking < Base

def initialize(opts = {})
  @default = :percent
  super
end

end
end

This sort-of works, but it renders as a 'normal' stacking and isn't settable.

If I want to do a quick hack by dropping in a new class definition or definitions, can you suggest how to go about it?

Otherwise, adding stacking to this library would be good.

I'm making a chart which has coloured bands on the yAxis like this: http://www.highcharts.com/demo/spline-plot-bands
http://api.highcharts.com/highcharts#yAxis.plotBands

But the plotBands on the yAxis only accepts a hash, meaning I can't put multiple bands on the same chart.

I would like to use dark-unica but it cannot find it, I assume because the included highcharts is out of date (dark unica is from 7 months ago)?

Also I would suggest somewhere in the readme specifying that you need to add
//= require highcharts in the application.js

Given the following, the second will overwrite the first...

chart.series(name: 'foo', ...)
chart.series(name: 'bar', ...)

Highcharts allows for the provision of multiple series, but this Ruby interface doesn't. I'm guessing you didn't need that?

While I am working on a fix which adds an array to Highcharts::Series, and requires a change to the Highcharts class to handle series differently, if you get to it first however...
