Bug ID: 171507
Summary: FILEOPEN: ChartEx axis majorUnit/minorUnit attributes
not imported from cx:valScaling
Product: LibreOffice
Version: unspecified
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Chart
Assignee: [email protected]
Reporter: [email protected]
When opening a .docx or .pptx file containing a ChartEx chart (cx:chart) with
custom axis scaling, the majorUnit and minorUnit attributes on the
cx:valScaling element are ignored. This causes charts with explicitly set tick
mark intervals to lose their axis scaling on import, falling back to
auto-calculated values.
The model fields (AxisModel::mofMajorUnit, mofMinorUnit) and the converter code
(AxisConverter::convertFromModel) already fully support these values. The
attributes were commented out in CxAxisContext with a TODO noting "need to
implement AttributeList method" for a non-existent getValAxisUnit() method.
Since majorUnit and minorUnit are simple double values (same type as the
already-working max and min attributes), the existing getDouble() method is the
correct approach.
Steps to reproduce:
1. In Microsoft Office, create a chart with custom axis major/minor unit values
2. Save as .docx or .pptx
3. Open in LibreOffice
Expected: Chart axis tick marks match the intervals set in Microsoft Office
Actual: Axis tick intervals fall back to auto-calculated defaults
