OpenFlashChart Version 2.0.0 11/14/2008
==============
1) rails ofc2_test_app
2) cd ofc2_test_app
3) script/plugin install http://github.com/pullmonkey/open_flash_chart.git -r test
4) script/generate controller test_it
5) Add the following to the test_it_controller.rb in RAILS_ROOT/app/controllers:
class TestItController < ApplicationController
def index
respond_to do |wants|
wants.html {
@graph = open_flash_chart_object( 600, 300, url_for( :action => 'index', :format => :json ) )
}
wants.json {
chart = OpenFlashChart.new( "MY TITLE" ) do |c|
c << BarGlass.new( :values => (1..10).sort_by{rand} )
end
render :text => chart, :layout => false
}
end
end
end
6) Add the following to index.html.erb in RAILS_ROOT/app/views/test_it/:
<html>
<head>
<script type="text/javascript" src="/javascripts/swfobject.js"></script>
</head>
<body>
<%= @graph %>
</body>
</html>
7) script/server
8) Let me know how it goes, thanks.
