            Bug ID: 324858
           Summary: Scale bar displays nonlinear integer values.
    Classification: Unclassified
           Product: marble
           Version: 1.6.0 (KDE 4.11.0)
          Platform: openSUSE RPMs
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
          Assignee: marble-bugs at kde.org

The scale bar plugin rescales as the map is zoomed, of course, and occasionally
displays integer values.  Some of these integer values, though spaced
linearily, are non linear in value.  E.g., starting snapped to Zoom 15, we have
(in miles):
0, 0.36, 0.72
Now we zoom out in small increments, and get:
0, 0.40, 0.80
0, 0.60, 1.20
and other values.  All is fine so far. Finally an integer value, but this is
fine, too:
0, 2, 4
So we keep zooming, looking for integer values:
0, 1, 3, 5
This is non linear, though spaced linearily. It is hard to tell what is
correct.  Continuing:
0, 2, 4, 6 linear
0, 2, 5, 8 nonlinear
0, 6, 12 linear
Thereafter, we seen to get even integer values which are always linear.


Reproducible: Always
