Stock charts currently ignore upDownBars tag and its subsidiary gapWidth, upBars, and downBars tags when reading, and hard-codes those tags on write. As a result, the sample reproductions of stock charts in the 32* series aren't faithful to the originals. This PR fixes samples 1, 2, and 5. Samples 3 and 4 are reproduced better, but they require currently unsupported secondary axes (issue PHPOffice#560, issue PHPOffice#1072, and PR PHPOffice#1073 were closed as stale; see also PHPOffice/PHPExcel#1037). I will start to look at those, but it could take a while, and I don't think there's a reason to delay this in the meantime. Charts which depended on the hard-coded values written by the Xlsx Chart writer will be slightly different as a result of this change. To restore the hard-coded behavior: ```php $plotArea->setGapWidth(300); $plotArea->setUseUpBars(true); $plotArea->setUseDownBars(true); ``` The new behavior is demonstrated in 33_Chart_create_stock. The old behavior is demonstrated (with the code above) in new 33_Chart_create_stock2.

It appears that the secondary Y axis is still not supported ! |
|
I'm afraid so. I haven't made any headway in figuring out how to implement it. |
