I have the following code:

		),
	    "options"=>array(
	        "chartArea"=>array(
				left=>50,
				right=>10,   // set this to adjust the legend with, shift the chartarea to left

            )
	    ),
		"colorScheme"=>array(
			"orange"

    ));
    ?>
</div>

How can I realize something like displaying the summed result in the title such as this:

 "title"=>"Operierte Patienten (nach Operationsdatum) (n = My_sum_result_here)",
