* 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.
These changes have already been implemented twice, and been regressed twice. I'll try once more (with a different approach), then give up ...
As configured, Phpstan running under Php7 reports no errors. However, running under Php8, it reports 100 (!) errors. The vast majority of these are due to two reasons:
- renaming parameters in Php builtin functions in preparation for named parameters.
- using the new class GdImage rather than type resource as the argument type for many image-based functions.
Regardless of the cause, this will be a problem sooner or later. This PR is an attempt to get ahead of that problem. For source members, it mostly adds annotations or updates doc-blocks. Only 2 members have changes to executable code, and these are very minor - BitWise and Writer/Xlsx. For test members, all baseline errors are deleted and the code is fixed. Php7 and Php8 both report no errors with this configuration.
PR #2088 is having major merge problems. This is partly because it moves some tests from Reader to Reader/Xlsx. Making this move beforehand may help. Or it may make things worse, but they are already bad enough that I am contemplating redoing the PR. If I do that, having this done beforehand will make things easier.
This PR does nothing but move some tests. This will make it easier to test changes to Xlsx Reader without having to run each test individually, or without having to run tests for all the other readers at the same time.
