public
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
VectorXYDataset and
VectorXYDataset methods instead.
Parameters: series the series index. item the item index.
Returns: The vector (possibly null
).
public 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 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.
