Constructor Detail

DefaultWindDataset

public DefaultWindDataset()
Constructs a new, empty, WindDataset.


DefaultWindDataset

public DefaultWindDataset(java.lang.Object[][][] data)
Constructs a WindDataset based on the specified data.

Parameters:
data - the wind dataset.

DefaultWindDataset

public DefaultWindDataset(java.lang.String[] seriesNames,
                          java.lang.Object[][][] data)
Constructs a WindDataset based on the specified data.

Parameters:
seriesNames - the names of the series.
data - the wind dataset.

DefaultWindDataset

public DefaultWindDataset(java.util.List seriesNames,
                          java.lang.Object[][][] data)
Constructs a WindDataset based on the specified data.

Parameters:
seriesNames - the names of the series.
data - the wind dataset.
Method Detail

getSeriesCount

public int getSeriesCount()
Returns the number of series in the dataset.

Specified by:
getSeriesCount in interface SeriesDataset
Specified by:
getSeriesCount in class AbstractSeriesDataset
Returns:
The number of series in the dataset.

getItemCount

public int getItemCount(int series)
Returns the number of items in a series.

Specified by:
getItemCount in interface XYDataset
Parameters:
series - The series (zero-based index).
Returns:
The number of items in a series.

getSeriesName

public java.lang.String getSeriesName(int series)
Returns the name of a series.

Specified by:
getSeriesName in interface SeriesDataset
Specified by:
getSeriesName in class AbstractSeriesDataset
Parameters:
series - The series (zero-based index).
Returns:
The name of the specified series.

getXValue

public java.lang.Number getXValue(int series,
                                  int item)
Returns the x-value for one item within a series. This should represent a point in time, encoded as milliseconds in the same way as java.util.Date.

Specified by:
getXValue in interface XYDataset
Parameters:
series - The series (zero-based index).
item - The item (zero-based index).
Returns:
The x-value for the item within the series.

getYValue

public java.lang.Number getYValue(int series,
                                  int item)
Returns the y-value for one item within a series. This maps to the getWindForce(...) method and is implemented because WindDataset is an extension of XYDataset.

Specified by:
getYValue in interface XYDataset
Parameters:
series - The series (zero-based index).
item - The item (zero-based index).
Returns:
The y-value for the item within the series.

getWindDirection

public java.lang.Number getWindDirection(int series,
                                         int item)
Returns the wind direction for one item within a series. This is a number between 0 and 12, like the numbers on a clock face.

Specified by:
getWindDirection in interface WindDataset
Parameters:
series - The series (zero-based index).
item - The item (zero-based index).
Returns:
The wind direction for the item within the series.

getWindForce

public java.lang.Number getWindForce(int series,
                                     int item)
Returns the wind force for one item within a series. This is a number between 0 and 12, as defined by the Beaufort scale.

Specified by:
getWindForce in interface WindDataset
Parameters:
series - The series (zero-based index).
item - The item (zero-based index).
Returns:
The wind force for the item within the series.

seriesNameListFromDataArray

public static java.util.List seriesNameListFromDataArray(java.lang.Object[][] data)
Utility method for automatically generating series names.

Parameters:
data - the wind dataset.
Returns:
an array of Series N with N = { 1 .. data.length }.
