This is the OFC chart model.
Use this model to configure chart title, axes, legends, labels, and draw-able elements in your chart. You add an chart type to the chart model, for example...
ChartModel cm = new ChartModel("Sales by Region"); PieChart pie = new PieChart(); pie.addValues(10, 30, 40, 20); cm.addChartConfig(pie);
