Public Methods
public abstract Vector getVector (int series, int item)
Returns the vector for an item in a series. Depending on the particular
dataset implementation, this may involve creating a new Vector
instance --- if you are just interested in the x and y components,
use the getVectorXValue(int, int) and
getVectorYValue(int, int) methods instead.
Parameters
| series | the series index. |
|---|---|
| item | the item index. |
Returns
- The vector (possibly
null).
public abstract double getVectorXValue (int series, int item)
Returns the x-component of the vector for an item in a series.
Parameters
| series | the series index. |
|---|---|
| item | the item index. |
Returns
- The x-component of the vector.
public abstract double getVectorYValue (int series, int item)
Returns the y-component of the vector for an item in a series.
Parameters
| series | the series index. |
|---|---|
| item | the item index. |
Returns
- The y-component of the vector.
