Fork not exactly in sync with vendor folder. Vendor folder has 1.8.1 while this is based on the branch 1.8. Need to sync via the release rather than branch.
I simply could could not migrate to PhpSpreadsheet due to my workplace setting.
My workplace's legacy project used PHPExcel a lot and eventually I ended up modifying its core code to change some styling and color schemes which the original version didn't have.
That's what's here. Branch 1.8 is the fork and 1.8.1j is original version code (1.8->1.8.1 if I'm not mistaken) changes along with my changes. I haven't tried to take the code by tag and 1.8.2 isn't here because my project used 1.8.1.
Full credit goes this question at Stack Overflow PHPExcel graph design (border, graph color, graph inner position). I used IIIOXIII's answer and applied Waqleh's answer to make my own custom class with those said changes, thus keeping the original writer Excel2007 untouched.
Ending and resuming original readme.
