5.1.3 Chart Data Model

Simple data model ChartDataModel is used for all data types, when the data is not stacked. If you want to stack data you must create simple data models (ChartDataModel) anyway.

Setting ChartDataModel: 

1
2
3
4
5
6
//sets ChartDataModel with 2 columns
ChartDataModel list1 = new ChartDataModel(2); 
list1.add(new Object[] {1,2 });
//sets ChartDataModel with 3 columns
ChartDataModel list2 = new ChartDataModel(3); 
list2.add(new Object[] {"one",2,3 });
