This example modifies the Icon Pie Chart example by using a semi-transparent donut instead of a pie, and using metallic background color.

# The data for the pie chart
$data = array(72, 18, 15, 12);

$labels = array("Sunny", "Cloudy", "Rainy", "Snowy");

# The icons for the sectors
$icons = array("sun.png", "cloud.png", "rain.png", "snowy.png");

# Create a PieChart object of size 400 x 300 pixels
$c = new PieChart(400, 300);

# Use the semi-transparent palette for this chart
$c->setColors($transparentPalette);

# Set the background to metallic light blue (CCFFFF), with a black border and 1 pixel
# 3D border effect,
$c->setBackground(metalColor(0xccccff), 0x000000, 1);

#Set directory for loading images to current script directory
#Need when running under Microsoft IIS

# Set donut center at (200, 175), and outer/inner radii as 100/50 pixels
$c->setDonutSize(200, 175, 100, 50);

# Add a title box using 15 pts Times Bold Italic font and metallic blue (8888FF)
# background color
$textBoxObj = $c->addTitle("Weather Profile in Wonderland", "timesbi.ttf", 15);
$textBoxObj->setBackground(metalColor(0x8888ff));

# Set the pie data and the pie labels
$c->setData($data, $labels);

# Add icons to the chart as a custom field

$c->setLabelFormat(
    "<*block,valign=absmiddle*><*img={field0}*> <*block*>{label}\n{percent}%<*/*>".

# Draw the pie in 3D with variable 3D depths
$c->set3D2($depths);

# Set the start angle to 225 degrees may improve layout when the depths of the sector
# are sorted in descending order, because it ensures the tallest sector is at the
# back.
$c->setStartAngle(225);

# output the chart
