public class PointDataSet<N extends java.lang.Number>
extends java.util.ArrayList<Point<N>>
implements DataSet

Store data sets in a dynamic Generics ArrayList of Points. Prefer this object instead of ArrayDataSet if you plan to alter the points of this data sets afterwards its creation.

If your data are not only numerical, consider using a GenericDataSet instead.

objclass - The class of this PointDataSet. For example for Double precision numbers, this parameter should be Double.class

array - The array containing the primitive data

Returns:

The produced PointDataSet of class objclass

Throws:

java.lang.ArrayStoreException - If some misconfiguration is performed on the provided array object
