Property Value

Type	Description
Boolean	true to extrapolate the Trend Line to negative infinity; otherwise, false.

Remarks

The chart automatically extrapolates the Trend Line to infinity (beyond the point’s argument in the positive direction of the axis). You can also extrapolate the Trend Line to negative infinity or limit the Trend Line to its points.

Set the TrendLine.ExtrapolateToInfinity property to false to limit the Trend Line to the point.

Set the ExtrapolateToNegativeInfinity property to true to extrapolate the Trend Line to negative infinity.

Refer to the following topic for more information: Trend Lines.
