the code :

require ‘rubygems’
require ‘ruport’
require ‘ruport/util’

class GraphReportController < Ruport::Report

renders_as_graph

def renderable_data(format)

graph = Graph(%w[a b c d e])
graph.series [1,2,3,4,5], “foo”
graph.series [11,22,70,2,19], “bar”
draw_graph(graph,
:title => “Graph”, :labels =>“Label”)

send_data(graph.to_blob, :disposition => ‘inline’, :type =>

‘image/png’, :filename => “foo.png”)
return graph
end

end

GraphReportController.generate do |r|
r.as(:png, :title => “My Graph”,
:labels => {0 => ‘2003’, 2 => ‘2004’, 4 => ‘2005’},
:file => “my_graph.png”
)
end
