3D Pyramid Chart

This example extends the Simple Pyramid Chart example by viewing the pyramid in 3D, using custom colors, inserting gaps between pyramid layers, and adding labels to both the center and the right side of the pyramid layers.

Specify 3D viewing angles using PyramidChart.setViewAngle.
Specify custom colors using BaseChart.setColors.
Insert gaps between pyramid layers using PyramidChart.setLayerGap
Add labels to the center and to the right side of the pyramid layers using PyramidChart.setCenterLabel and PyramidChart.setRightLabel.

# The data for the pyramid chart
$data = array(156, 123, 211, 179);

# The labels for the pyramid chart
$labels = array("Corporate Tax", "Working Capital", "Re-investment", "Dividend");

# The colors for the pyramid layers
$colors = array(0x66aaee, 0xeebb22, 0xcccccc, 0xcc88ff);

# Create a PyramidChart object of size 500 x 400 pixels
$c = new PyramidChart(500, 400);

# Set the pyramid center at (200, 180), and width x height to 150 x 300 pixels
$c->setPyramidSize(200, 180, 150, 300);

# Set the elevation to 15 degrees
$c->setViewAngle(15);

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

# Set the layer colors to the given colors
$c->setColors2(DataColor, $colors);

# Leave 1% gaps between layers
$c->setLayerGap(0.01);

# Add labels at the center of the pyramid layers using Arial Bold font. The labels will show the
# percentage of the layers.
$c->setCenterLabel("{percent}%", "Arial Bold");

# Add labels at the right side of the pyramid layers using Arial Bold font. The labels will have two
# lines showing the layer name and value.
$c->setRightLabel("{label}\nUS\$ {value}M", "Arial Bold");

# Output the chart
$viewer = new WebChartViewer("chart1");
$viewer->setChart($c, SVG);

# Include tool tip for the chart
$viewer->setImageMap($c->getHTMLImageMap("", "", "title='{label}: US\$ {value}M ({percent}%)'"));
