            Bug ID: 140555
           Summary: Mean disappears from charts after save when Linear is
                    added to charts.
           Product: LibreOffice
           Version: 7.1.0.3 release
          Hardware: All
                OS: Windows (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Chart
          Assignee: libreoffice-bugs at lists.freedesktop.org

Description:
When creating a line chart in LibreCalc I've added both a Linear and Mean
lines. When saved and then re-opened the Mean line is gone.

Steps to Reproduce:
1. Open LibreOffice
2. Open LibreCalc
3. Enter in column 1A the word "Date"
4. Enter in column 1B the word "Value"
5. Enter in column 2A through 11A the following values, 01/01/21 through
01/10/21 - use drag from 1A if you wish for auto date create per cell.
6. Enter in column 2B through 11B the following values: 1, 2, 3, 4, 5, 3, 4, 5,
3, 1
7. Select (highlight) 1A through 11B
8. Select Chart from Insert menu
9. Right click on chart, select Edit
10. Click on any data column to select all data bars
11. Right click and select Insert Mean Value Line
12. Right click and select Insert Trend Line
13. Click OK for Trend to make Trend properties box close
14. Select File, Save As - save as .xlsx (note: I also saved as .OSD and when I
tried to reload, LibreOffice kept crashing on the intro loading screen. I had
to kill it using task manager. When re-loaded I had to open in safe mode, close
and then open in normal mode. Then it brought up the .osd file and all appeared
ok. I normally use .xlsx to maintain compatibility with MS Office users.)
15. Close LibreOffice
16. Open LibreOffice and open the file just saved or use the recent documents
menu to open the file. 

The issue is able to be duplicated running in Safe Mode. It doesn't appear to
be a corrupt profile issue. 

Actual Results:
The Linear line remains in the chart. The Mean line disappears. 

Expected Results:
For the Mean line to not disappear. 


Reproducible: Always


User Profile Reset: Yes


OpenGL enabled: Yes
