Constructor Details

DataColumn

public DataColumn(DataColumnType type,
 String name)

Creates a DataColumn with initial capacity 100 and increment 100.

Parameters:

name - the column name

DataColumn

public DataColumn(DataColumnType type,
 String name,
 int initCap,
 int increment)

Create a DataColumn

Parameters:

name - the column name

initCap - the initial capacity

increment - the increment when the array grows.

Method Details

getHistoData

public HistoData getHistoData()

This gets the histogram data, which for non-histograms will be null.

Returns:

the histogram data

setHistoData

protected void setHistoData(HistoData histo)

Set the histogram data container

Parameters:

histo - the histogram data

getHistoData2D

public Histo2DData getHistoData2D()

This gets the histogram 2D data, which for non-histograms will be null.

Returns:

the histogram 2D data

setHistoData2D

protected void setHistoData2D(Histo2DData histo2D)

Set the histogram 2D data container

Parameters:

histo2D - the histogram 2D data

isHistogram1D

public boolean isHistogram1D()

Checks whether this is a 1D histogram

Returns:

true if this is a 1D histogram

isHistogram2D

public boolean isHistogram2D()

Checks whether this is a 2D histogram

Returns:

true if this is a 2D histogram

isVisible

public boolean isVisible()

Check whether this "curve" is visible. Only relevant for Y columns.

Returns:

the visibility flag

setName
