Method Detail

getData2D

double[][] getData2D()

Gets a 2D array of data. The first column, double[0][] often contains x-values; Remaining columns often contain y values. May return null if data not yet generated or object does not support 2D data.

Returns:

double[][]

getData3D

double[][][] getData3D()

Gets a 3D array of data. May return null if data not yet generated or object does not support 3D data.

Returns:

double[][][]

getDatasets

java.util.ArrayList<Dataset> getDatasets()

Gets a list of OSP Datasets. May return null if data not yet generated or object does not support Datasets.

Returns:

list of Datasets

getName

java.lang.String getName()

The name of the data

Returns:

the name

getLineColors

java.awt.Color[] getLineColors()

Line color to use for this data

Returns:

a color

getFillColors

java.awt.Color[] getFillColors()

Fill color to use for this data

Returns:

a color

getColumnNames

java.lang.String[] getColumnNames()

The column names to be used in the data display tool

Returns:

an array of names

getDataList

java.util.List<Data> getDataList()

Some Data objects (e.g., a Group) do not contain data, but a list of Data objects which do. This method is used by Data displaying tools to create as many pages as needed.

Returns:

a list of Data objects, or null if this object contains data

getID

int getID()

Returns a unique identifier for this Data

Returns:

the ID number

setID

void setID(int id)

Sets the ID number of this Data

Parameters:

id - the ID number
