public class ChartDataModel
extends Observable
implements EditableChartable
ChartDataModel is an arbitrary data source for JClass products. A DataSource object assumes that data can be retrieved as rows and columns. It is up to the product to interpret the data in the appropriate manner. For example, Chart will interpret every row pair as a series of x and y values. DataSources can be chained together as Observable/Observer pairs in order to transform the data. An example would be a DataSource that transposes the row and column values of its DataSource and presents that to a JClass product.
