Hello everybody
I have a problem with the displaying of a line diagram and I am currently stuck. My line curve first rises and then shows strong jumps (see picture in the attachment). I would like to make two changes:
1) I would like to show only the line up to the maximum value as a solid line and show the progression after that by a dashed line. If this is not possible, I would like to delete everything after the maximum value. Do I have to disconnect the line somehow?
2) I would like to smooth the curve up to the maximum value by the upper values. Which function do I use best for this?
Thanks a lot for your help!

1) If you double-click on the line to open the Plot Details dialog. Under the Line tab, you can set the Style to Line, Dash, or refer to a column. You can add a new column to the worksheet as line style, and have the line style refer to that column.
2) For smoothing, you can probably use this envelope tool.

Thanks for your help. But unfortunately, non of your recommendations works (or I do not know how to apply them correct)
For your second advice f.e. regardless how many smoothing points I choese, it just gets worse and worse by increasing the number (picture)

The data is not saved with the project. Could you also share the Excel file ASTM1002_104 Kopie.xlsx? Thanks.

Please check the attached project file. You could use menu Gadgets->Quick Peaks... to find the peaks on the curve. Then you can either connect those peaks or do a curve fitting to get the trend curve.
In Book1, I added col(C) as the line style column (1 = solid, 2 = dashed). Double-click on the line on the graph, and you could see the line style is referring to that column.
