Enum Constant Detail

Logarithmic

public static final TrendlineType Logarithmic

Uses the equation y = c ln x + b to calculate that the least squares fit through points.

Linear

public static final TrendlineType Linear

Uses the linear equation y = mx + b to calculate that the least squares fit through points.

Polynomial

public static final TrendlineType Polynomial

Uses an equation to calculate that the least squares fit through points.

Power

public static final TrendlineType Power

Uses an equation to calculate that the least squares fit through points.

Exponential

public static final TrendlineType Exponential

Uses an equation to calculate that the least squares fit through points.

MovingAvg

public static final TrendlineType MovingAvg

Uses a sequence of averages computed from parts of the data series. The number of points equals the total number of points in the series less the number specified for the period.

Method Detail

values

public static TrendlineType[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (TrendlineType c : TrendlineType.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static TrendlineType valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null
