* Additional Support for Chart DataSeriesValues
Fix#2863. DataSeriesValues now extends Properties, allowing it to share code in common with Axis and Gridlines. This causes some minor breakages; in particular line width is now initialized to null instead of Excel's default value, and is specified in points, as the user would expect from Excel, rather than the value stored in Xml.
This change:
- adds support for 1 or 2 marker colors.
- adds support for `smoothLine` to DataSeriesValues.
- will determine `catAx` or `valAx` for Axis based on what is read from the Xml when available, rather than guessing based on format. (Another minor break.)
- reads `formatCode` and `sourceLinked` for Axis.
- correct 2 uses of `$plotSeriesRef` to `$plotSeriesIndex` in Writer/Xlsx/Chart.
- pushes coverage over 90% for Chart (88.70% overall).
* Update Change Log
I had updated previously but forgot to stage the member.
* Adopt Some Suggestions
Incorporate some changes suggested by @bridgeplayr.
* Use ChartColor for DSV Fill And Font Text
DataSeriesValues Fill could be a scalar or an array, so I saved it till last.
* Some Final Cleanup
No code changes.
Illustrate even more of the new features in existing sample files.
Deprecate *_ARGB in Properties/ChartColors in favor of *_RGB, because it uses only 6 hex digits. The alpha value is stored separately.
Because even if it doesn't make a difference in practice, it is
technically more correct to call static methods statically. It
also better advertise that those methods can be used from any context.
