Constructor Detail

PseudoArrayDataModel

public PseudoArrayDataModel(ArrayDataModel model,
                            AxisMapper xMapper,
                            AxisMapper yMapper)

Method Detail

dispose

public void dispose()

Disposes object

finalize

protected void finalize()
                 throws java.lang.Throwable

Overrides:

finalize in class java.lang.Object

Throws:

java.lang.Throwable

modelChanged

public void modelChanged(DataModelChangeEvent event)

Specified by:

modelChanged in interface ChartDataModelListener

isValueNull

public boolean isValueNull(int index)

Checks if there are points in the data model (stacked ones or not stacked ones) where both points are null

Parameters:

index - index of the data point

Returns:

true if specified index is of null value

getValueAt

public java.lang.Object getValueAt(DataColumnType valType,
                                   int index)

calculateNullValue

public java.lang.Object calculateNullValue(ArrayDataModel model,
                                           DataColumnType valType,
                                           int index)

containsNulls

public boolean containsNulls(DataColumnType valType,
                             int index)

Checks if there are nulls in the data model contained in the lower parts of the stacked series

Parameters:

index - index of the data point

Returns:

true if there are nulls to be calculated

calculateNullPointValue

public java.lang.Object calculateNullPointValue(ArrayDataModel model,

Parameters:

model - data model from where to retrieve x

index - index of the data point

Returns:

x value at specified index

getY

protected java.lang.Object getY(ArrayDataModel model,
                                int index)

Gets y value

Parameters:

model - data model from where to retrieve y

index - index of the data point

Returns:

y value at specified index
