Graphs with Gruff

class GraphController < BaseTimeController
def pages
g = Gruff::Pie.new(“500×350”)
g.title = “All Pages”
@current_user.pages.each do |page|
g.data(page.title, [page.total])
end
send_data(g.to_blob,
:disposition => ‘inline’,
:type => ‘image/png’,
:filename => “timers.png”)
end
end

Pretty easy! Wasn’t it. Note the code above shows only the first of the graphs. Now if only I could find out how to set the minimum of the Bar chart to 0 instead of the minimum of the serie. Any help is appreciated?
