Remarks

The Trendline object is a member of the Trendlines collection. The Trendlines collection contains all the Trendline objects for a single series.

Use Trendlines(index), where index is the trendline index number, to return a single Trendline object.

The index number denotes the order in which the trendlines were added to the series. Trendlines(1) is the first trendline added to the series, and Trendlines(Trendlines.Count) is the last one added.

Properties

Application	Returns an Application object that represents the Microsoft Excel application.
Backward	Returns or sets the number of periods (or units on a scatter chart) that the trendline extends backward.
Backward2	Returns or sets the number of periods (or units on a scatter chart) that the trendline extends backward. Read/write.

Creator	Returns a 32-bit integer that indicates the application in which this object was created.
DataLabel	Returns a DataLabel object that represents the data label associated with the point or trendline.
DisplayEquation	True if the equation for the trendline is displayed on the chart (in the same data label as the R-squared value). Setting this property to True automatically turns on data labels.
DisplayRSquared	True if the R-squared value of the trendline is displayed on the chart (in the same data label as the equation). Setting this property to True automatically turns on data labels.

Forward2	Returns or sets the number of periods (or units on a scatter chart) that the trendline extends forward. Read/write.
Index	Returns the index number of the object within the collection of similar objects.
Intercept	Returns or sets the point where the trendline crosses the value axis.
InterceptIsAuto	True if the point where the trendline crosses the value axis is automatically determined by the regression.
Name	Returns or sets the name of the object.
NameIsAuto	True if Microsoft Excel automatically determines the name of the trendline.
Order	Returns or sets the trendline order (an integer greater than 1) when the trendline type is xlPolynomial.
Parent	Returns the parent object for the specified object.
Period	Returns or sets the period for the moving-average trendline.
