Trendlines object (Excel)

  • Article

A collection of all the Trendline objects for the specified series.

Remarks

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

Example

Use the Trendlines method of the Series object to return the Trendlines collection. The following example displays the number of trendlines for series one on Chart1.

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

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 in embedded chart one on Sheet1.

Worksheets("sheet1").ChartObjects(1).Chart.SeriesCollection(1) _ 
 .Trendlines.Add type:=xlLinear, name:="Linear Trend"

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 in embedded chart one on worksheet one. 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.

Worksheets(1).ChartObjects(1).Chart. _ 
 SeriesCollection(1).Trendlines(1).Type = xlMovingAvg
