                                      int category)

Returns the start value for the interval for a given series and category.

Parameters:

series - the series (zero-based index).

category - the category (zero-based index).

Returns:

the start value (possibly null).

getStartValue

public java.lang.Number getStartValue(java.lang.Comparable series,
                                      java.lang.Comparable category)

Returns the start value for the interval for a given series and category.

Parameters:

series - the series key.

category - the category key.

Returns:

the start value (possibly null).

getEndValue

public java.lang.Number getEndValue(int series,
                                    int category)

Returns the end value for the interval for a given series and category.

Parameters:

series - the series (zero-based index).

category - the category (zero-based index).

Returns:

the end value (possibly null).

getEndValue

public java.lang.Number getEndValue(java.lang.Comparable series,
                                    java.lang.Comparable category)
