// ChartDirector for ColdFusion API Access Point
cd = CreateObject("java", "ChartDirector.CFChart");

// A utility to allow us to create arrays with data in one line of code
function Array() {
    var result = ArrayNew(1);
    var i = 0;
    for (i = 1; i LTE ArrayLen(arguments); i = i + 1)
        result[i] = arguments[i];
    return result;
}

// The data for the pie chart
data = Array(25, 18, 15, 12, 8, 30, 35);

// The labels for the pie chart
labels = Array("Labor", "Licenses", "Taxes", "Legal", "Insurance", "Facilities", "Production");

// Create a PieChart object of size 360 x 300 pixels
c = cd.PieChart(360, 300);

// Set the center of the pie at (180, 140) and the radius to 100 pixels
c.setPieSize(180, 140, 100);

// Set the pie data and the pie labels
c.setData(data, labels);

// Output the chart
chart1URL = c.makeSession(GetPageContext(), "chart1");

// Include tool tip for the chart
imageMap1 = c.getHTMLImageMap("", "", "title='{label}: US${value}K ({percent}%)'");
