Represents a trendline in a chart.
Assembly: Microsoft.Office.Interop.Word (in Microsoft.Office.Interop.Word.dll)
Use Trendlines (Index), where Index is the trendline index number, to return a single 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.
The following example changes the trendline type for the first series of the first chart in the active document. If the series has no trendline, this example will fail.
