* More Chart Fixes
Taking up where #2828 left off. Most of the following changes are demonstrated in 32readwriteChartWithImages1:
- Adds support for "scheme" colors (because rgb, theme, and index colors just weren't enough for Excel) for DataSeriesValues. See issue #2299.
- For chart titles (including axis labels), rather than a font name, Excel supplies a 3-fold series of font names for Latin, East Asian, and Complex Scripts. New properties `latin`, `eastAsian`, and `complexScript` are added to the Font class. I frankly have no idea how, or even if, you can set these in Excel; my test case (sample 32readwriteScatterChart7) is a result of manually editing the XML.
- Add support for subscript/superscript to chart titles. This requires a new property `baseLine` in Font (positive=superscript negative=subscript baseline value says how high/low).
- Support for underscore with different scheme color than its text, using a new string property `uSchemeClr` in Font.
- Support for extra options for strikethrough, using a new string property `strikeType` in Font.
- Support for extra options for underscore type, using the existing string property `underline` in Font.
- I do not anticipate that any of the new Font properties will be used except for chart titles.
- If no default font overrides are found for a Rich Text element in chart titles, and no explicit font overrides are found for a Run under such an element, the font element of the Run is set to null.
- PhpSpreadsheet will always write a tag `a:pPr` and, underneath that, an empty tag `a:defRPr`, for default font settings for chart titles and axis labels. Combined with the previous bullet item, this will prevent PhpSpreadsheet from inadvertently overriding the Excel defaults (18 point bold Calibri for chart title, 10 point bold Calibri for axis labels).
- Axis labels will now be written to XML in the same manner as chart titles. Among other considerations, this means that they can now have colors. Fix#2700. Supersedes PR #2701. Demonstrated in sample 32readwriteStockChart5.
* Fix Some Chart Corruption
Fix#2817, where @bridgeplayr gives an excellent description of the problem and how it should be solved.
* Fix Bubble Charts
Sample produced corrupt output - see issue #2763. After a lot of research, solution was just re-ordering of parameters in a single function call.
Bubble 3D had not been supported at all. It is now.
Surface Charts remain corrupted.
* Some Fixes for Scatter Charts
Chart issues have been pouring in recently. This is a partial response to issue #2762. It implements "no joins" for scatter charts, as well as having the reader and writer handle "point size", "line width", and "color" for markers. A new boolean property `scatterLines`, with setter and getter, is added to DataSeriesValues to handle joins (default is true which means scatter plot points *are* joined by lines). Some, but not yet all, default font properties for the chart title are handled (color and, surprisingly, font name present challenges).
With these changes, sample 32readwriteScatterChart1.xlsx now looks closer to its source. There are still some differences (x-axis changes), but I think this change is already large enough. I can work on the other problems later.
The code for reading charts has not yet been converted to be namespace aware. Having a tiny island of aware code in a sea of unaware makes no sense to me, so some of the new code is likewise unaware. I hope to be able to get to it eventually, but, among other considerations, it is difficult to generate suitable test cases.
* Add Formal Tests
Essentially the same as the corresponding Samples, but with formal assertions.
* Clean Up Some Code in Reader/Xlsx/Chart
Having added code to support default font attributes as well as element-specific font attributes for chart captions, there was duplicated code between the default and specific sections. I hope that this PR makes the code easier to follow.
* Add Support for Font Name and Color to XLSX Chart Titles
XML layout for these in new files differs from what program was expecting. Not sure if program expectations were wrong, or if this is a change to Excel since initial development.
* Minor Improvement
Handle theoretical case where Chart title has text but no font information.
* Support Bezier Curve and Scaling of X-Axis on Scatter Plot
For Bezier, need to specify `<c:smooth>` tag in addition to already supplied `<c:scatterStyle val="smoothMarker">`
For X-Axis, scatter needs to supply both X and y axis as `<c:valAx>` rather than `<c:catAx>` for X.
* Real Errors Identified in Calculation by Scrutinizer
Before Scrutinizer broke, I took a look at the remaining 43 errors which it categorized as 'major'. Most of these were false positives, but, in the case of Calculation and Reader/Xlsx/Chart, I was able to determine that its analysis of some of the problems was correct. There is little point addressing the false positives until it starts working again, but we should fix the real errors.
This PR addresses the real errors in Calculation.
- A test for `$pCellParent` should have been a test for `$pCellWorksheet`.
- A test for `$operand1Data['reference']` should have been a test for `$operand1Data['value']`.
- A test for `$operand2Data['reference']` should have been a test for `$operand2Data['value']`.
* Fix Attempt to Erroneously Call trim on Array
Fix#2780. Warning message is being issued when getting calculated value of cell with value `=INDIRECT(ADDRESS(ROW(),COLUMN()-2))/$C$4`. This appears to be the case for all recent (and probably not so recent) releases; it is not a result of changes to the code base. Fix added to this PR because the erring section of code was proximate to code already changed in the PR. Test added.
* Minor Code Changes
Apply some suggestions from @MarkBaker
PHP 8.2 is supposed to deprecate the use of `['self', 'functionname']` for callables, suggesting the use of `[self::class, 'functionname']` instead. We made this change in a recent PR, and, while I'm thinking about it, I'll fix the remaining 2 modules with this construction. Vlookup is already adequately covered in unit tests. Reader/Xls/MD5 is not; a unit test is added.
Fix#2768. DateFormatter handles only one of six special formats for time intervals `[h] [hh] [m] [mm] [s] [ss]`. This PR extends support to the rest. There should be no more than one of these in any format string. Although it certainly could make sense to treat `[d] [dd]` in the same manner, Excel does not seem to support those.
Interesting observations - hours and minutes are truncated (presumably because they may be followed by minutes and seconds), but seconds are rounded. Also, there are some floating point issues, which fortunately showed up for the example in the original issue. There, the time interval was 1.15, which should evaluate to a minutes value of 1656 (as it does in Excel). However, on my system it evaluated to 1655 because of a rounding error in the 13th decimal place. To overcome this, values are rounded to 10 decimal places before truncating.
I suspect that scrutiniser may complain that the pass-by-reference values in an expression like `sscanf($coord, '%[A-Z]%d', $column, $row)` don't exist; but PHP handles that without issue, creating the variables as needed, and phpstan has no problems with that, so scrutiniser shouldn't treat it as an issue. There's no point in adding code (even if it's just pre-defining call-by-reference arguments) when it's unnecessary overhead.
Dependabot submitted PRs #2719 and #2720 to upgrade Phpstan. As with most Phpstan upgrades, there are new error messages; this PR is an attempt to fix all 58 of the new problems in order to allow the upgrade to proceed.
Most of these fixes involve the addition of doc-block type annotations, often involving the assignment of the 'objectionable' portion of the statement to a new variable. Some use explicit casting when I am sure that's safe. Some (Reader/Ods) involve defeating result caching by Phpstan.
* Add editAs Property for 2-cell Anchor Drawings
This change builds on PR #2532 (@naotake51 as PR #2532), using ideas from PR #2237 (@AdamGaskins), which has had changes requested for several months. It covers a lot of the same ground as 2532. In Excel, two-cell anchor drawings can be edited as "twocell", "onecell", or "absolute". This PR adds support for those options, with a sample file that demonstrates the difference in addition to unit tests. Several other tests are added to improve the spotty coverage for Drawings.
There have been several other tickets referencing two cell anchors, including issue #1159 and PR #1160 (@sgarwood, who also added support for editAs), PR #643, and issue #126, all now closed but not necessarily entirely resolved. I will try to ensure that those tickets are addressed with this one.
And, in trying to make sure 1160 is covered, I stumbled upon a bug. If you use the same image resource to create two+ memory drawings, the MemoryDrawing destructor for the first will cause the rest to generate a very long warning message. This is not a problem for Php8+, only for Php7-. I have suppressed the message in the MemoryDrawing constructor. 1160 went stale due to an unresolved test error, but I don't think this was the problem. At any rate, its test works now.
* Scrutinizer
It reported 1 minor issue (fixed normally), and 2 major. One is fixed with a kludge. The other is a case where Scrutinizer's analysis is just wrong, and I can't figure out a kludge. But I was able to add an annotation (the first time I've managed to get one past phpcs/php-cs-fixer). We'll see.
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.
Initial implementation of Excel's tables feature (i.e. Select Home >
Format as Table in Excel App).
Tables are similar to AutoFilter but tables have other advantages like
named ranges, easy formatting, totals row and header row with filter.
Tables can also be converted to charts and pivot tables easily.
Usage:
$table = new Table();
$table->setName('Sales_Data');
$table->setRange('A1:D17');
$spreadsheet->getActiveSheet()->addTable($table);
In this Commit:
- Added Table API with initial support for header and totals row.
- Added complete styling options for Table.
- Added Xlsx Writer for Table.
- Added samples.
- Covered with unit tests.
To be done:
- Filter expressions similar to AutoFilter.
- Precalucate formulas for totals row (Check sample 2).
- Table named ranges in formulas and calculation.
* Add two cell anhor drawing.
* Add "Support for two cell anchor drawing of images." to CHANGELOG.md
* Add pull-request link to "Support for two cell anchor drawing of images." of CHANGELOG.md
You can set up a conditional style to, say, apply to cells equal to boolean values. For such conditions, the Excel XML specifies `TRUE` or `FALSE`. It is noteworthy that false matches empty cells as well as FALSE, but not 0; similarly TRUE does not match 1. The Xlsx Writer just casts these values to string, which will not work properly. The Xlsx Reader treats the values as strings, so it won't work properly either. This PR corrects both. Also the doc blocks in Style/Conditional allow bool in some places, but not in others; these are corrected but no executable code is changed there.
These changes were already implemented as PR #2428. They were, alas, regressed by PR #2585. If at first you don't succeed ...

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 tweaks only the Phpstan configuration files, without changing any PhpSpreadsheet code. For the small number of test members involved, the code is fixed. Php7 and Php8 both report no errors with this configuration.
Because this involves no changes to code, and because Phpstan baseline is a common cause of merge difficulties, I will probably merge this in a day or two, more quickly than I customarily do.
Note that this method is used when translating Excel functions between en and other locale languages, as well as when converting formulae between different spreadsheet formats (e.g. Ods to Excel)
Nor is this a perfect solution, as there may still be issues when function calls have array arguments that themselves contain function calls; but it's still better than the current logic
* Initial work on implementing Array-enabled for the HLOOKUP() and VLOOKUP() functions
* In the MATCH() function, we should also use `evaluateArrayArgumentsIgnore()` because the lookupvalue and matchType arguments can be array arguments, but lookupArray is always a dataset matrix
* Split Information functions into a dedicated class and namespace and categorise as Value or Error
* Refactor all error functions into the new ExcelError class
