While creating a Flex chart from an ArrayCollection is relatively simple, using data from an xml for the chart is apparently not as straightforward, especially if the xml has childnodes deeper than a couple of levels. This example demonstrates how to convert xml (returned from an HttpService call to a servlet) to an ArrayCollection and use it as the datasource for a chart.

One of the ways to integrate a Java application with a Flex front end is by using Httpservice with XML. Aimed primarily at Java developers new to Flex, this quick start guide describes how to populate a flex table using xml returned by a servlet.
