ActiveRecord::Olap::ChartHelper

This module contains functions to display OLAP cubes using chart images. The charts will be generated using the Google Chart API, which is accessed through the gchartrb gem. Before you can use these methods, make sure that the module is included as helper module so the methods are available in your views:

class MyOlapController < ActionController::Base

  helper ActiveRecord::Olap::ChartHelper

  …
