This has not so much to do with Rails, but at least I think you can use them for free.

Create any chart for any business need. Explore our gallery of Bar, Column, Line, Area, Gantt, Pareto, Finance, Performance and 150+ pre-made charts.

You could use Google charts (http://code.google.com/apis/chart/)

Use the gchartrb gem, then you can write helpers like this:

      GoogleChart::BarChart.new('600x200', nil, :vertical, false) do

bc>

        bc.data nil, result, '623d2a'         bc.axis :x, :labels => labels, :color => '000000'         bc.axis :y, :labels => [0,(result.max/2).to_i,result.max], :color => '000000'         bc.width_spacing_options :bar_width => 25, :bar_spacing => 30, :group_spacing => 40

        @result = image_tag(bc.to_url)       end
