Adding Credits
To display credits on the chart in the bottom right hand corner, use the Chart Credit tag with the text and href attributes.
This tag must be nested in the Chart Display tag.
<chart:display response="response" title="Current Products" type="column" facet-name="current_products">
<chart:credit href="http://twigkit.com" text="twigkit.com"></chart:credit>
</chart:display>
