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.
