Class ChartFactory

java.lang.Object
  com.fusioncharts.ChartFactory

public class ChartFactory
extends java.lang.Object

The ChartFactory class allows a chart object to be created and to associate graphs and series. It is made flexible so that we will be able to re-use this factory to build charts for multiple chart packages (ie: FusionCharts, Jfreechart) in the future. 20090325 - Implementation of methods to generate chart info for fusion charts David Lai
