Perhaps someguys could know, I want to modify jpgraph.

    function StockPlot(&$datay,$datax=false) {

    $this->numpoints /= $this->iTupleSize;

this is original code and i want to change like following

    function StockPlot(&$datay,$datax=false, &$numy) {

    $this->numpoints = count($numy);

$this->numpoints is already existed. Do you know why this doesn't work?
Thank you in advance.
