Subject: Re: scruffy question

Hi,

Finally, I'm trying to test Scruffy in my 'application_helper.rb' :

def render_scruffy_graph
    graph = Scruffy::Graph.new
    graph.title = "Comparative Agent Performance"
    graph.value_formatter = 
Scruffy::Formatters::Percentage.new(:precision => 0)
    graph.add :stacked do |stacked|
      stacked.add :bar, 'remco', [30, 60, 49, 29, 100, 120]
      stacked.add :bar, 'peter', [120, 240, 0, 100, 140, 20]
      stacked.add :bar, 'femmie', [10, 10, 90, 20, 40, 10]
    end
    graph.point_markers = ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun']
    graph.render(:width => 800, :as => 'PNG')
end

with :
<%= render_scruffy_graph %> #in my 'show.rhtml' file

But the image is returned as blob/string.

So I've got something like that :

Thx
