Usage

About javascript Assets notes: for Rails 2.x/3.0.x 1.you need manually put jquery/highcharts js to public/javascript 2.modify your layout html Sample Code: <%= javascript_include_tag "http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js" %> <%= javascript_include_tag :high_charts %> 3. add gem name in your config/environment.rb config.gem "lazy_high_charts" 4.done!

For Rails 3.1 In your Gemfile, add this line: gem 'lazy_high_charts', '~> 1.1.5' then execuate command: Rails g lazy_high_charts:install

Usage in Controller:

 @h = LazyHighCharts::HighChart.new('graph') do |f|
    f.options[:chart][:defaultSeriesType] = "area"
    f.series(:name=>'John', :data=>[3, 20, 3, 5, 4, 10, 12 ,3, 5,6,7,7,80,9,9])
    f.series(:name=>'Jane', :data=> [1, 3, 4, 3, 3, 5, 4,-46,7,8,8,9,9,0,0,9] )
  end

Without overriding entire option , (only change a specific option index):

 @h = LazyHighCharts::HighChart.new('graph') do |f|
  .....
      f.options[:chart][:defaultSeriesType] = "area"
      f.options[:chart][:inverted] = true
      f.options[:legend][:layout] = "horizontal"
      f.options[:xAxis][:categories] = ["uno" ,"dos" , "tres" , "cuatro"]
 ......

Overriding entire option:

 @h = LazyHighCharts::HighChart.new('graph') do |f|
   .....
      f.xAxis(:categories => @days.reverse! , :labels=>{:rotation=>-45 , :align => 'right'})
      f.chart({:defaultSeriesType=>"spline" , :renderTo => "myRenderArea" , :inverted => true})
   .....

Usage in layout:

<%= javascript_include_tag :high_charts %>

Usage in view:

<%= high_chart("my_id", @h) %>

Passing formatting options in the view to the helper block , because all the helper options declared in the controller are converted in strict/valid json (quoted key); so we need to extend the json object with some js.

  <%= high_chart("my_id", @h) do |c| %>
     	<%= "options.tooltip.formatter = function() { return '<b>HEY!!!'+ this.series.name +'</b><br/>'+ this.x +': '+ this.y +' units';}" %>
     	<%= "options.xAxis.labels.formatter = function() { return 'ho';}" %>
     	<%= "options.yAxis.labels.formatter = function() { return 'hey';}" %>
   <%end %>

HighStock Support:

 ##just call HighChart Helper this way:

   <%= high_stock("my_id", @h) %>
