I want the legends to appear on the left side. Now it is coming on top of pie chart

  PieChart::create(array(
        "title"=>"Sale Of Category",
        "dataSource"=>$newStore,
        "columns"=>array(
            "category",
            "cost"=>array(
                "type"=>"number",
                //"prefix"=>"$",
            )
        )
    ));

Is there any property to change the legends to left side. position vertically . instead of top horizontal?

I am using chartjs. both pie chart and polar chart legends needs to be shifted to left and aligned vertically.

Thank you. As given in the above link setting legend option to left worked.
