highcharts_exporting

Highcharts server exporting for Rails.

Installation

NOTE: Phatomjs is required, please install it before.

Add this line to your application's Gemfile:

gem 'highcharts_exporting'

And then execute:

$ bundle

Or install it yourself as:

$ gem install highcharts_exporting

Usage

Add highcharts_controller.rb.

class HighchartsController < ApplicationController
  include HighchartsExporting::Exporter

end

Add route in routes.rb.

post 'highcharts/export'

Config url /highcharts/export in highcharts options.

$('#container').highcharts({
  ...
  exporting: {
    url: '/highcharts/export'
    ...
  }
});

Hot it works

Default Hightcharts privides two implementations of languages(PHP and Java) as export server, for more details.

However Hightcharts also privides a image convert script executing in Phantomjs environment for exporting. I just use Phantomjs gem to invoke highcharts-convert.js with params sent by client. More details.
