# cd someproject
# rails plugin install git://github.com/pullmonkey/open_flash_chart.git
# cp vendor/plugins/open_flash_chart/assets/javascripts/swfobject.js public/javascripts/
# cp vendor/plugins/open_flash_chart/assets/open-flash-chart.swf public/

Wirte chart generation codes in some controller:

class TestItController < ApplicationController
  def index
    @graph = open_flash_chart_object(600,300,"/test_it/graph_code")
  end

  def graph_code
    title = Title.new("MY TITLE")
    bar = BarGlass.new
    bar.set_values([1,2,3,4,5,6,7,8,9])
    chart = OpenFlashChart.new
    chart.set_title(title)
    chart.add_element(bar)
    render :text => chart.to_s
