Hi @Mike Linacre ,
Here is the example code for Xojo that makes a graph in Excel, adds a trendline, and names the trendline:
[code]Sub Action() Handles Action
Dim excel as new ExcelApplication
excel.Workbooks.Add
excel.Visible = True
//Add data
Dim i as integer
For i = 1 to 50
excel.Range(“A” + CStr(i)).Value = i
excel.Range(“B” + CStr(i)).Value = i1.1i
Next
//Create a chart
excel.Range(“A1:B50”).Select_
excel.ActiveSheet.Shapes.AddChart2(240, Office.xlXYScatterSmoothNoMarkers).Select_
excel.ActiveChart.SetSourceData(excel.Range(“Sheet1!$A$1:$B$50”))
//Add a trendline
excel.ActiveChart.FullSeriesCollection(1).Select_
excel.ActiveChart.FullSeriesCollection(1).Trendlines.Add
excel.ActiveChart.FullSeriesCollection(1).Name = “Upper two-sided”
End Sub
[/code]
Does this work on your computer?
Edit: This renames all of the lines. Is this what you wanted?
