Constructor Detail

AggregateXYSeries

public AggregateXYSeries(Series x,
                         Series y)

Note: This series object stores references to x and y. Changing the contents of x or y will change the contents of this series.

Parameters:

x - Series of X values.

y - Series of Y values.

Throws:

NullPointerException - (unchecked exception) Thrown if x or y is null.
