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
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.
