php jpgraph plot advice

Recommended Posts

Hey guys, I have been reading all the tutorials and class reference for JpGraph but I was just wondering if its possible to plot individual points without using an array? for example in libchart  the following code is used

but I can't figure out how do do this in JpGraph as all the examples use arrays. Any help would be great, Thanks.

<?php
include "libchart/libchart.php";

header("Content-type: image/png");

$chart = new VerticalChart(500,250);

$chart->addPoint(new Point("Jan 2005", 273));
$chart->addPoint(new Point("Feb 2005", 321));
$chart->addPoint(new Point("March 2005", 442));
$chart->addPoint(new Point("April 2005", 711));

$chart->setTitle("Monthly usage for www.example.com");
$chart->render();
?>
