Parameters:

series - the series index (zero-based).

item - the item index (zero-based).

Returns:

The z-value (possibly null).

getZValue

double getZValue(int series,
                 int item)

Returns the z-value (as a double primitive) for an item within a series.

Parameters:

series - the series (zero-based index).

item - the item (zero-based index).

Returns:

The z-value.
