Simplize using Fusionchartfree for ruby on rails
First you should generate swf files
rails g easyfsf
and then you can render chart by using helper method
example
<%= render_sm_chart(“a”, “Pie2D”, [‘a’,‘b’,‘c’], [1,2,3]) %> <%= render_sm_chart(“b”, “Column3D”, [‘a’,‘b’,‘c’], [=> “se1”, :color => “FF0000”,:value_list => [1,2,3], => “se2”, :color => “F660AB”, :value_list => [3,4,5]]) %>
