3D Pie Chart

This example extends the Simple Pie Chart example by drawing the chart in 3D, adding a title, and exploding a sector.

Add a title to the chart using BaseChart.addTitle.
Draw the pie in 3D using PieChart.set3D.
Explode a sector using PieChart.setExplode.

# Create a PieChart object of size 360 x 300 pixels

# Set the center of the pie at (180, 140) and the radius to 100 pixels

# Add a title to the pie chart
$c->addTitle("Project Cost Breakdown");

# Draw the pie in 3D

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

# Explode the 1st sector (index = 0)
$c->setExplode(0);

# Output the chart
$c->makeChart("threedpie.png");
