Method Detail

getSeriesCount

public int getSeriesCount()

Returns the number of series in the dataset.

Specified by:

getSeriesCount in interface org.jfree.data.general.SeriesDataset

Specified by:

getSeriesCount in class org.jfree.data.general.AbstractSeriesDataset

Returns:

The series count.

getSeriesKey

public java.lang.Comparable getSeriesKey(int series)

Returns the key for a series.

Specified by:

getSeriesKey in interface org.jfree.data.general.SeriesDataset

Specified by:

getSeriesKey in class org.jfree.data.general.AbstractSeriesDataset

Parameters:

series - the series (zero-based index).

Returns:

The key for the series.

getItemCount

public int getItemCount(int series)

Returns the number of items in a series.

Specified by:

getItemCount in interface org.jfree.data.xy.XYDataset

Parameters:

series - the series (zero-based index).

Returns:

The number of items within the series.

getX

public java.lang.Number getX(int series,
                    int item)

Returns the x-value for an item within a series.

The implementation is responsible for ensuring that the x-values are presented in ascending order.

Specified by:

getX in interface org.jfree.data.xy.XYDataset

Parameters:

series - the series (zero-based index).

item - the item (zero-based index).

Returns:

                    int item)

Returns the y-value for an item within a series.

Specified by:

getY in interface org.jfree.data.xy.XYDataset

Parameters:

series - the series (zero-based index).

item - the item (zero-based index).

Returns:

The y-value.

getZ

public java.lang.Number getZ(int series,
                    int item)

Returns the z-value for the specified series and item.

Specified by:

getZ in interface org.jfree.data.xy.XYZDataset

Parameters:

series - the series index (zero-based).

item - the item index (zero-based).

Returns:

The value.
