Getting data into the chart

The functions layer will contain the LoadChartData function. This function will load the XML data into the chart component. The chart will be referenced by using the instance name MyChart.

The first thing to do is create the function on the functions layer and set up a reference for the chart node in the XML document.

function LoadChartData() {
var BaseNode = thisXML.childNodes[0];

We will use the BaseNode to reference other nodes within the XML document. The chart data is contained in the child nodes of the base node. These are the chartItem nodes.

The following code loads the label and values for each chart item into an array and then adds them to the ChartData data source. I chose the names DataLabel and DataValue for the fieldnames in the data source.

//set up arrays
var ArrLabel = new Array();
var ArrValue = new Array();
var ThisNode;
//create datasource
var ChartData = new DataProviderClass();
//get Chart Data
for (var i=0; i < BaseNode.childNodes.length; i++) {
ThisNode = BaseNode.childNodes[i];
ArrLabel[i] = ThisNode.attributes["ChartLabel"];
ArrValue[i] = ThisNode.attributes["ChartValue"];
ChartData.addItem({DataLabel:ArrLabel[i], DataValue:ArrValue[i]});

Note: You don't have to load the chart labels and values into an array first, but it might be useful if you're going to use the information in some other way.

The next step is to link the datasource to the MyChart object and indicate which fields contain the labels and values.


Test the movie and you should see a chart populated with the values from your XML file.

The complete code for the functions frame is on the next page.

» Description: Hmm... what to say about this one? It's reminiscent of the closing notes of the opening music from the Three Stooges done in a church organ style with a closing cymbal crash. I'll give this one away gratis, but feel free to check out my free loops and potential upcoming license-mandated ones over in the respective part of Flashkit.
