Because they tend to clutter our code a lot and unfortunately, there are
lots of false positives. Instead, it would probably be better to deal
with false positives out of band, via the Scrutinizer web UI.
While we might never be able to have 100% of our code strict, we can at
the very least do it for all of our tests. This ensures that our tests
are using our API with the types as intended by the test author, and not
silently be cast to what our API requires.
* Fix Unintential Deprecated Calls - Everything Else
I think it's best to install these before PR #3166. This one, which I hope to be the last in this series, does have some minor changes to source code, as well as to doc-blocks and to test members which continue to inadvertently use calls to deprecated functions.
* Some Remaining Deprecations in Tests
Fix them now.
* Minor Docblock Updates
Worksheet::unprotectCellsByColumnAndRow was incorrect. Other changes are cosmetic, leading to slightly better documentation.
* Update Worksheet.php
* Move Gridlines from Chart to Axis
This could, I hope, be my last major change to Chart for a while. When I first noticed this problem, I thought it would be a breaking change. However, although this change establishes some deprecations, I don't think it breaks anything. Major and minor gridlines had only been settable by the Chart constructor. This PR moves them where they belong, to Axis (eexisting Chart constructor code will still work). This allows them to be specified from both X and Y axis.
Chart is now entirely covered except for 2 statements, one deprecated and one that I just can't figure out. 99.71% for Charts, 88.96% overall. All references to the Chart directory in Phpstan baseline are eliminated.
* Minor Fixes, Unit Tests
Line style color type should default to null not prstClr.
Chart X-axis and Y-axis should alway be Axis, never null.
Add some unit tests.
* More Tests, Some Improvements
Make it easier to change line styles, adding an alternate method besides a setter function with at least a dozen parameters.
Unit testing now results in 100% coverage for Axis and Properties. All the properties in methods in Gridlines were more or less duplicated in Axis, and these duplications are moved to the common ancestor Properties. So, there isn't anything left in Gridlines. PhpSpreadsheet Chart is now over 85% covered (it was below 35% until recently).
Properties are in many cases set to default to null/null-string, rather than the default values they receive from Excel, and are not written to Xml if unchanged. This is consistent with how Excel behaves. A new property `crossBetween` is added to Axis, and, with support for that added to Xlsx Reader and Writer, some minor Sample peculiarities are corrected, in particular, the charts were sometimes slightly truncated on the left and right edges.
