枚举常量详细资料

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.

方法详细资料

values

public static TrendlineType[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

返回:

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

valueOf

public static TrendlineType valueOf(String name)

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

参数:

name - 要返回的枚举常量的名称。

返回:

返回带有指定名称的枚举常量

抛出:

IllegalArgumentException - if this enum class has no constant with the specified name

NullPointerException - 如果参数为空值
