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.

// The data for the pyramid chart
double[] data = {156, 123, 211, 179};

// The labels for the pyramid chart
String[] labels = {"Funds", "Bonds", "Stocks", "Cash"};

// Create a PyramidChart object of size 360 x 360 pixels
PyramidChart 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
WebChartViewer viewer = new WebChartViewer(request, "chart1");
viewer.setChart(c, Chart.SVG);

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