Previous pie chart's colors are lost when loading an existing file #2219
Labels
Comments
Thank you for raising this issue, and for the nice sample code you provided. Pie charts store their fill colors in a manner which PhpSpreadsheet is not yet set up to read. So, (a) it is not necessary to add a second chart to demonstrate this problem, and (b) it may apply to other types of charts as well. I am investigating what needs to be done to add the proper support to the Xlsx reader. |

Fix PHPOffice#2219. Address some, but not all, issues mentioned in PHPOffice#2863. For Pie Charts, fill color is stored in XML as part of dPt node, which had been ignored by Reader/Xlsx/Chart. Add support for it, including when specified as schemeClr or prstClr rather than srgbClr. Add support for prstClr in other cases where schemeClr is supported.
