            Bug ID: 132480
           Summary: Lines are not spaced correctly for log scale graphs
                    that don't start at a power of 10
           Product: LibreOffice
           Version: 6.4.2.2 release
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Calc
          Assignee: libreoffice-bugs at lists.freedesktop.org

Description:
If you make a graph with X axis starting at 10, and ending at 1000, the minor
grid lines should (and will) be drawn at:

10
20
30
40
50
60
70
80
90
100
200
300
400
500
600
700
800
900
1000

If you make a graph with X axis starting at 20, and ending at 2000, the minor
grid lines should be drawn at:

20
30
40
50
60
70
80
90
100
200
300
400
500
600
700
800
900
1000
2000

However, if you try the second case in LibreOffice Calc, it draws them with the
same spacing as the first case, just with different labels, so the grid lines
are actually at mostly useless numbers:

20
40
60
80
100
120
140
160
180
200
400
600
800
1000
1200
1400
1600
1800
2000

Instead, the lines should always fall on multiples of 10, regardless of
starting point, not on arbitrary numbers.

Steps to Reproduce:
1. Create a graph
2. Insert minor grid lines
3. Set spacing to logarithmic
4. Set starting point at anything other than a power of 10

Actual Results:
See above

Expected Results:
See above


Reproducible: Always


User Profile Reset: No
