Simple Pyramid Chart

This example demonstrates the basic steps in creating pyramid charts.

Create a PyramidChart object using PyramidChart.PyramidChart.
Specify the center and radius of the pie using PyramidChart.setPyramidSize.
Specify the data used to draw the pie using PyramidChart.setData.
Add labels at the center of the pyramid layers using PyramidChart.setCenterLabel
Assign the chart to the WebChartViewer using WebChartViewer.setChart, and insert it to the web page using WebChartViewer.renderHTML.
Generate tool tips for the chart using BaseChart.getHTMLImageMap.

<?php
require_once("../lib/phpchartdir.php");

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

# The labels for the pyramid chart
$labels = array("Funds", "Bonds", "Stocks", "Cash");

# Create a PyramidChart object of size 360 x 360 pixels
$c = new PyramidChart(360, 360);

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

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

# Add labels at the center of the pyramid layers using Arial Bold font. The labels will have two
# lines showing the layer name and percentage.
$c->setCenterLabel("{label}\n{percent}%", "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}%)'"));
