Hi,

Thank You.

  Re: Throw java.lang.NullPointerException for setData of PieChart

Hi Joseph,

ChartDirector for ColdFusion comes with a "3D Pie Chart" sample code at
"cfdemo/threedpie.cfm". Please kindly try this sample code in your ColdFusion server to
see if it works normally.

If the sample code works, but your actual code does not work, the error may be related
to some specific to your code. In this case, is it possible to provide me with an example
that can create the problem? The example preferrably should be as simple as possible
(just contain the charting part) and using hard coded data, so I may be able to test it.

I am thinking, if setData crashes in your code, it may be related to the data used. For
testing, may be you can comment out the original setData line, and replace it with the
following hard coded data to see if it works. If the hard coded data works, but your
actual data do not work, is it possible to provide a dump of your actual data and labels?

// 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");

//assuming the variable for the PieChart object is "myChart"
myChart.setData(data, labels);

Regards
Peter Kwan
