                          java.lang.Object[][][] data)

Constructs a WindDataset based on the specified data.

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.
