 org.jfree.data.xy.DefaultWindDataset
| Method Summary | |
| public boolean | equals(Object obj)
Checks this WindDataset for equality with an arbitrary
object. | | public int | getItemCount(int series)
Returns the number of items in a series.
Parameters:
series - the series (zero-based index). | | public int | getSeriesCount()
Returns the number of series in the dataset. | | public Comparable | getSeriesKey(int series)
Returns the key for a series.
Parameters:
series - the series (zero-based index). | | public Number | getWindDirection(int series, int item)
Returns the wind direction for one item within a series. | | public Number | getWindForce(int series, int item)
Returns the wind force for one item within a series. | | public Number | getX(int series, int item)
Returns the x-value for one item within a series. | | public Number | getY(int series, int item)
Returns the y-value for one item within a series. | | public static List | seriesNameListFromDataArray(Object[][] data)
Utility method for automatically generating series names.
Parameters:
data - the wind data (null not permitted). |
| DefaultWindDataset | | public DefaultWindDataset()(Code) | | Constructs a new, empty, dataset. Since there are currently no methods
to add data to an existing dataset, you should probably use a different
constructor.
|
| DefaultWindDataset | | public DefaultWindDataset(Object[][][] data)(Code) | | Constructs a dataset based on the specified data array.
Parameters:
data - the data (null not permitted).
throws:
NullPointerException - if data is null. |
| DefaultWindDataset | | public DefaultWindDataset(String[] seriesNames, Object[][][] data)(Code) | | Constructs a dataset based on the specified data array.
Parameters:
seriesNames - the names of the series (null not permitted).
Parameters:
data - the wind data.
throws:
NullPointerException - if seriesNames is null. |
| DefaultWindDataset | | public DefaultWindDataset(List seriesKeys, Object[][][] data)(Code) | | Constructs a dataset based on the specified data array. The array
can contain multiple series, each series can contain multiple items,
and each item is as follows:
data[series][item][0] - the date (either a
Date or a Number that is the milliseconds
since 1-Jan-1970);data[series][item][1] - the wind direction (1 - 12,
like the numbers on a clock face);data[series][item][2] - the wind force (1 - 12 on the
Beaufort scale)
Parameters:
seriesKeys - the names of the series (null not permitted).
Parameters:
data - the wind dataset (null not permitted).
throws:
IllegalArgumentException - if seriesKeys is null.
throws:
IllegalArgumentException - if the number of series keys does notmatch the number of series in the array.
throws:
NullPointerException - if data is null. |
| equals | | public boolean equals(Object obj)(Code) | | Checks this WindDataset for equality with an arbitrary
object. This method returns true if and only if:
obj is not null;obj is an instance of
DefaultWindDataset;- both datasets have the same number of series containing identical
values.
Parameters:
obj - the object (null permitted). A boolean. |
| getItemCount | | public int getItemCount(int series)(Code) | | Returns the number of items in a series.
Parameters:
series - the series (zero-based index). The item count. |
| getSeriesCount | | public int getSeriesCount()(Code) | | Returns the number of series in the dataset.
The series count. |
| getSeriesKey | | public Comparable getSeriesKey(int series)(Code) | | Returns the key for a series.
Parameters:
series - the series (zero-based index). The series key. |
| getWindDirection | | public Number getWindDirection(int series, int item)(Code) | | Returns the wind direction for one item within a series. This is a
number between 0 and 12, like the numbers on an upside-down clock face.
Parameters:
series - the series (zero-based index).
Parameters:
item - the item (zero-based index). The wind direction for the item within the series. |
| getWindForce | | public Number getWindForce(int series, int item)(Code) | | Returns the wind force for one item within a series. This is a number
between 0 and 12, as defined by the Beaufort scale.
Parameters:
series - the series (zero-based index).
Parameters:
item - the item (zero-based index). The wind force for the item within the series. |
| getX | | public Number getX(int series, int item)(Code) | | 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.
Parameters:
series - the series (zero-based index).
Parameters:
item - the item (zero-based index). The x-value for the item within the series. |
| getY | | public Number getY(int series, int item)(Code) | | Returns the y-value for one item within a series. This maps to the
DefaultWindDataset.getWindForce(int,int) method and is implemented because
WindDataset is an extension of
XYDataset .
Parameters:
series - the series (zero-based index).
Parameters:
item - the item (zero-based index). The y-value for the item within the series. |
| seriesNameListFromDataArray | | public static List seriesNameListFromDataArray(Object[][] data)(Code) | | Utility method for automatically generating series names.
Parameters:
data - the wind data (null not permitted). An array of Series N with N = { 1 .. data.length }.
throws:
NullPointerException - if data is null. |
