Trendlines Object (PowerPoint)

Published: July 16, 2012

Represents a collection of all the Trendline objects for the specified series.

Version Added: PowerPoint 2007

Each Trendline object represents a trendline in a chart. A trendline shows the trend, or direction, of data in a series.

Note Note

Although the following code applies to Microsoft Word, you can readily modify it to apply to PowerPoint.

Use the Trendlines method to return the Trendlines collection. The following example displays the number of trendlines for series one of the first chart in the active document.

With ActiveDocument.InlineShapes(1)

    If .HasChart Then

        MsgBox .Chart.SeriesCollection(1).Trendlines.Count

    End If

End With

NoteNote

Although the following code applies to Microsoft Word, you can readily modify it to apply to PowerPoint.

Use the Add method to create a new trendline and add it to the series. The following example adds a linear trendline to the first series for the first chart in the active document.

With ActiveDocument.InlineShapes(1)

    If .HasChart Then

        .Chart.SeriesCollection(1) _

            .Trendlines.Add Type:=xlLinear, Name:="Linear Trend"

    End If

End With

NoteNote

Although the following code applies to Microsoft Word, you can readily modify it to apply to PowerPoint.

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

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.

With ActiveDocument.InlineShapes(1)

    If .HasChart Then

        .Chart.SeriesCollection(1).Trendlines(1).Type = xlMovingAvg

    End If

End With
