jpgraph

[kirke]

Perhaps someguys could know, I want to modify jpgraph.

function StockPlot(&$dat ay,$datax=false ) {

$this->Plot($datay,$d atax);
$this->numpoints /= $this->iTupleSize;
}

this is original code and i want to change like following


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

$this->Plot($datay,$d atax);
$this->numpoints = count($numy);
}

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