# Set the plotarea at (45, 30) and of size 200 x 200 pixels
$c->setPlotArea(45, 30, 200, 200);


# Add a title to the chart using 12 pts Arial Bold Italic font
$c->addTitle("Web Grade", "arialbi.ttf", 12);

# Add a title to the y axis
$c->yAxis->setTitle("Web point");

# Add a title to the x axis
$c->xAxis->setTitle("Course name");

# Add a blue (0x6666ff) 3D line chart layer using the give data
$lineLayerObj = $c->addLineLayer($ydata, 0x6666ff);
$lineLayerObj->set3D();

# Set the labels on the x axis.
$c->xAxis->setLabels($labels);

# output the chart
header("Content-type: image/png");
print($c->makeChart2(PNG));
?>
