This is a start in addressing issue #2965 (and earlier issue #749). Chart Titles are usually entered as strings or Rich Text strings, and PhpSpreadsheet supports that. They can also be entered as formulas (typically a pointer to a cell with the title text), and, not only did PhpSpreadsheet not support that, it threw an exception when reading a spreadsheet that did so. This change does: - eliminate the exception - set a static chart title when it can determine it from the Xml This change does not: - fully support dynamic titles (e.g. if you change the contents of the source cell, or delete or insert cells or rows or columns) - permit the user to set the title to a formula - allow the use of formulas when writing a chart title to a spreadsheet - provide styling for titles when it has read them as a formula
