簡単な例:
getchart.php:
<?php
// get the q parameter from URL
$q = $_REQUEST["q"];
//Includes
include "../../sources/TChart.php";
$chart1 = new TChart(600,450);
$chart1->getChart()->getHeader()->setText($q);
$chart1->getAspect()->setView3D(false);
$line1 = new Line($chart1->getChart());
$line1->setColor(Color::RED());
$chart1->addSeries($line1);
// Speed optimization
$chart1->getChart()->setAutoRepaint(false);
for($t = 0; $t <= 10; ++$t) {
$line1->addXY($t, (10 + $t), Color::RED());
}
$chart1->getChart()->setAutoRepaint(true);
$chart1->render("chart1.png");
$rand=rand();
echo "chart1.png?rand=".$rand;
?>
Test.htmlという:

<head>
<script>
function showChart(str) {
var xmlhttp = new XMLHttpRequest();
xmlhttp.onreadystatechange = function() {
if (this.readyState == 4 && this.status == 200) {
var image = document.getElementById("get_img");
image.src = xmlhttp.responseText;
}
}
xmlhttp.open("GET", "getchart.php?q="+str, true);
xmlhttp.send();
}
