public class DataColumn
extends Dataset

DataColumn is a Dataset that represents a single column in a DataToolTable. The x-column name is always "row" and the x-points are always row numbers. Y-values may be shifted from their raw values. All values have the same shift.

Constructor Details

DataColumn

public DataColumn()

Constructs a DataColumn.

Method Details

setPoints

public void setPoints(double[] yPoints,
 int len)

Sets the y-column points. The x-column points are always row numbers.

Parameters:

yPoints - the y-column data points

setXYColumnNames

public void setXYColumnNames(String xName,
 String yName)

Overrides Dataset.setXYColumnNames method. The x-column name is always "row".

Overrides:

setXYColumnNames in class Dataset

Parameters:

xName - ignored

yName - the y-column name

setXYColumnNames

public void setXYColumnNames(String xName,
 String yName,
 String name)

Overrides Dataset.setXYColumnNames method. The x-column name is always "row".

Overrides:

setXYColumnNames in class Dataset

Parameters:

xName - ignored

yName - the y-column name

name - the dataset name

setXColumnVisible

public void setXColumnVisible(boolean b)

Overrides Dataset.setXColumnVisible method. The x-column is never visible.

Overrides:

setXColumnVisible in class Dataset

Parameters:

b - ignored

getYPoints

public double[] getYPoints()

Gets a copy of the ypoints array, with shift added if shifted.

Overrides:

getYPoints in class Dataset

Returns:

the y points (may be shifted)

getY

public double getY(int i)

Overrides:

getY in class Dataset

setShifted

public void setShifted(boolean shift)

Sets the shifted property to shift the values of all elements.

Overrides:

setShifted in class Dataset

Parameters:

shift - true to shift the values

isShifted

public boolean isShifted()

Gets the shifted property.

Overrides:

isShifted in class Dataset

Returns:

true if values are shifted

setShift

public boolean setShift(double shift)

Sets the shift used to shift the values of all elements.

Overrides:

setShift in class Dataset

Parameters:

shift - the shift

Returns:

true if shift was changed

getShift

public double getShift()

Gets the shift used to shift the values of all elements.

Overrides:

getShift in class Dataset

Returns:

the shift

getPreviousShift

public double getPreviousShift()

Gets the previous shift.

Returns:

the previous shift

setShiftedValue

public boolean setShiftedValue(int i,
 double value)

Overrides:

setShiftedValue in class Dataset

getLoader

public static XML.ObjectLoader getLoader()

Returns the XML.ObjectLoader for this class.

Returns:

the object loader
