[Solved] X-Y scatter chart lines disappeared

[alanack]

Windows 10, LibreOffice 7.4.3.2(64)

I've had a X-Y scatter chart I've used for years, on which I am continually adding and deleting data. For some reason the lines (one in positive numbers, one in negative) that average the data points have disappeared. I simply can't figure out how to get in there and add that those lines back. Thanks for your help!

Hi,
I checked your file on LO 7.4.3.2 and 7.3.7.2 and AOO 4.1.13 (on LinuxMint).
In each case the average lines (mean value lines) have not been defined (and thus did not exist).
To add these lines double click on diagram (edit mode) → select one data series → right hand click → Insert mean value line

After saving, closing and reopening the file the mean value lines still existed.
