Public Constructors
public XYBarDataset (XYDataset underlying, double barWidth)
Creates a new dataset.
Parameters
| underlying | the underlying dataset (null not
permitted). |
|---|---|
| barWidth | the width of the bars. |
Public Methods
public Object clone ()
Returns an independent copy of the dataset. Note that:
- the underlying dataset is only cloned if it implements the PublicCloneable interface;
- the listeners registered with this dataset are not carried over to the cloned dataset.
Returns
- An independent copy of the dataset.
Throws
| CloneNotSupportedException | if the dataset cannot be cloned for any reason. |
|---|
public void datasetChanged (DatasetChangeEvent event)
Receives notification of an dataset change event.
Parameters
| event | information about the event. |
|---|
public boolean equals (Object obj)
Tests this dataset for equality with an arbitrary object.
Parameters
| obj | the object (null permitted). |
|---|
Returns
- A boolean.
public double getBarWidth ()
public Number getEndX (int series, int item)
Returns the ending X value for the specified series and item.
Parameters
| series | the series index (zero-based). |
|---|---|
| item | the item index (zero-based). |
Returns
- The value.
public double getEndXValue (int series, int item)
Returns the ending x-value (as a double primitive) for an item within a series.
Parameters
| series | the series index (zero-based). |
|---|---|
| item | the item index (zero-based). |
Returns
- The value.
See Also
