* 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. |

PHPExcel vs PhpSpreadsheet ?
PhpSpreadsheet is the next version of PHPExcel. It breaks compatibility to dramatically improve the code base quality (namespaces, PSR compliance, use of latest PHP language features, etc.).
Because all efforts have shifted to PhpSpreadsheet, PHPExcel will no longer be maintained. All contributions for PHPExcel, patches and new features, should target PhpSpreadsheet master branch.
Do you need to migrate? There is an automated tool for that.
