public JCData3dIndex(com.klg.jclass.chart3d.Chart3dDataView dataView)

Constructor that creates a data index from a dataView and data.

Parameters:

dataView - the dataView this index is based upon

Method Detail

getDataView

public com.klg.jclass.chart3d.Chart3dDataView getDataView()

Gets the value of the DataView property. It contains the Chart3dDataView instance that holds the point that this data index class is referring to.

Returns:

the data view

setDataView

public void setDataView(com.klg.jclass.chart3d.Chart3dDataView dataView)

Sets the value of the DataView property. It contains the ChartDataView instance that holds the point that this data index class is referring to.

Parameters:

dataView - sets a new data view for this object

getObject

public Object getObject()

Gets the value of the Obj property. It is used by pick operations and contains the object picked (for example, a JCChart3dArea or JCLegend instance) by those operations.

Returns:

picked object

setObject

public void setObject(Object object)

Parameters:

object - picked object

getDistance

public double getDistance()

Gets the value of the Distance property. It is used by pick operations and contains the distance between the point selected and the nearest data point.

Returns:

distance from the selected point

setDistance

public void setDistance(double distance)

Sets the value of the Distance property. It is used by pick operations and contains the distance between the point selected and the nearest data point.

Parameters:

distance - the new distance from the data point

setChanged
