public class JCChartSwingDataSource

extends ChartDataSupport

implements EditableChartDataModel, LabelledChartDataModel, HoleValueChartDataModel, TableModelListener, ChartDataManageable, Serializable

JCChartSwingDataSource provides an intepretive layer between JCChart and data existing in a Swing TableModel format.

The most notable differences between them is the inversion of rows and columns - TableModel's rows are JCChart's columns, and vice versa. Also, TableModel provides no X values, and so these are generated here.

Constructor Detail

JCChartSwingDataSource

public JCChartSwingDataSource()

The default constructor. Makes an empty data source.

JCChartSwingDataSource

public JCChartSwingDataSource(TableModel model)

Constructor. Sets the table model to passed object.

Parameters:

model - The table model on which to base this datasource

JCChartSwingDataSource

public JCChartSwingDataSource(TableModel model,
                              String[] pointLabels,
                              String dataSourceName)

Constructor. Sets the table model to passed object, values for point labels, and a data source name.

Parameters:

model - The table model on which to base this datasource

pointLabels - A list of point labels for this data source

dataSourceName - The name of this data source

Method Detail

setDataItem

public boolean setDataItem(int seriesIndex,
                           int pointIndex,
