Problems with using Open Flash Charts library

Hi. I have download OpenFlashCharts library for RubyonRails. And when I try to make a chart a have problem with data for this chart code samples from examples which are on this web-site are'nt working http://pullmonkey.com/projects/open_flash_chart

for example

def piechart   @graph = open_flash_chart_object(500,250, '/projects/pie', false, '/projects/')   end   def pie         data =         5.times do |t|                 data << rand(10) + 5         end

        g = Graph.new         g.pie(60, '#505050', '#000000')         g.pie_values(data, %w(IE FireFox Opera Wii Other))         g.pie_slice_colors(%w(#d01fc3 #356aa0 #c79810))         g.set_tool_tip("#val#%")         g.title("Pie Chart", '{font-size:18px; color: #d01f3c}' )         render :text => g.render     end end

dont draw me a chart but when I put data for chart to /projects/pie/newfile this script draw me chart but problem is in that data must be generated automatically without putting data in another file.

Thanks for replies.
