Creating graph using Ruport

Rails
1

hi,
cud anybody plz tell how to veiw or show a graph that has been created
using the ruport gem…
i have created the graph n report refering
“http://ruportbook.com/introducing_ruport.html”. but at the end it is
not showing the graph on the browser.

This looks like something I can do. After much installation I try this
simple example and get the following error. I did find a simple example
that creates a pdf file, but I’d really like to make a graph. Any ideas
on what I have misconfigured?

This is on an iMac G5 with 3g of memory and lots of disk space.

the code:

this is the code i had written:------ for the reference

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
