Highcharts for Rails 3

modify from: lazy-high-charts, with Highcharts v2.1.5 and Rails 3

use: Highcharts

Demo

Support Env:

Rails3.0.8+/Ruby1.8.7+

Usage:

gem 'rails_highcharts'

rails g rails_highcharts:install

Usage in Controller:

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

Overriding entire option:

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

Usage in layout:

<%= javascript_include_tag :highcharts %> 
<!--[if IE]> <%= javascript_include_tag :ie_high_charts %> <![endif]-->

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 %>
