Multiple Charts with Chart Module? I need to present multiple graphs in a single page. Is it possible to do this using the Charts module? Up until now I have been using the following to return a chart to the page.

return theme('chart', array(
                      'chart' =&gt; $chart,
                    ));
After a while doing the following worked, I do not know why it did not work from the beginning : 

return theme('chart', array(
              'chart' =&gt; $chart,
              )).theme('chart', array(
              'chart' =&gt; $chart,
              ));
