All Known Subinterfaces:

CategoryModel, HiLoModel, PieModel, SingleValueCategoryModel, XYModel, XYZModel

```
public interface ChartModel
```
Chart Model is used to hold the data model for the chart.
- PieModel: one series of data objects. Each data object contains the category name and numeric value of a pie.
- CategoryModel: n series of data objects. Each data object contains the category name and associated numeric value .
- XYModel: n series of data objects. Each data object contains an (x,y) pair.
- XYZModel: n series of data objects. Each data object contains an (x,y,z) pair; since 3.5.0
This interface defines the data model for components like Chart use to get the value of data.
