Hi, 

I am playing around with Ruport and trying out the example. Here is the code that I copied from the documentation:

require "rubygems"

require "ruport"

require "ruport/util"

  class GraphReport < 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"

      return graph

    end

  end

  GraphReport.generate do |r|

    r.save_as("foo.svg", :template => :graph)

  end

I have installed ruport, ruport-util,Gruff. I get the following error:

 JRuby limited openssl loaded. http://jruby.org/openssl
gem install jruby-openssl for full support.

Is the :graph template not defined or changed ? . What am I missing ? 

Also I have following questions about Ruport and would appreciate if someone can help me here :

1] Can I generate graphs directly to a file without using UI . I tend to use putty/NX etc to run scripts overnight. 

2] Can I generate multiple graphs in parallel [batch ?] . Hopefully I can just create multiple threads in a code and have them generate graphs ?

Thanks for the support !

Pavan
