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 (Charts  |  Google for Developers)

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
