Zoomed account balance chart

SUMMARY
When one zooms a chart (using so-called rubber band zooming feature from
KDiagram project) axis ticks and labels are recalculated but they are
overridden with customized "hard labels". The number of axis ticks is
increasing and becomes grater than the count of hard labels, so the labels are
repeated in cycle. In and of itself, it is really a feature rather than a bug
but the feature works to our disadvantage in this case producing incorrect
ordinate axis labels.

STEPS TO REPRODUCE
1. Open any account ledger and click on "Show balance chart" button at the top.
2. Click and drag your left mouse button to zoom boxed area.

OBSERVED RESULT
Ordinate axis labels are incorrect and repeated in cycle.

EXPECTED RESULT
Ordinate axis labels should match zoomed chart's data.

SOFTWARE/OS VERSIONS
KDE Plasma Version: 5.18.4
