i am trying to create graphs using the ruport gem. even though it  
creates the graph “sales.png”. but it does not show it on the browser in  
the application.

“sorry something went wrong and it has been notified”

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
