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
