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

You could use Google charts ([Charts &nbsp;|&nbsp; Google for Developers](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

```
