Created attachment 158424 [details] Sample PPTX document
Created attachment 158425 [details] This is how it looks in Office 365 / PowerPoint
Created attachment 158426 [details] This is how it looks in LO This is how it looks in LibreOffice. Not readable well or hardly at all: - black text and dark background (hardly readable) - black text on darker green background (not readable well)
Created attachment 158427 [details] How it looks like in LO when switching to bar chart/stacked mode When switching to bar chart/stacked mode the issue persists, so I assume there is a general routine handling coloring that can be fixed.
Created attachment 158428 [details] This is how it looks in LO in regular bar chart mode (note the white on white lable missing on the fourth line) Switching to a regular bar chart, the fourth line has its label rendered white on white -- which is a little invisible. ;-)
I confirm that - the text color of pie segment 1 is black where it should be white and - the label positions are somewhat different in LO than in Powerpoint. In my opinion your bug report title is somewhat misleading since the "black text on dark background" results from the wrong positioning of the labels (ON the pie vs. NEXT TO the pie slice). If you agree please adjust the title of this bug report. I will then confirm it.

I am torn on this: from a positioning perspective, isn't LibreOffice doing a better job re that segment than Office 365? If the text color was different (= readable) I would prefer LibreOffice's choice. In the case of the bar char/stacked (cf. comment #3) positioning cannot be changed, so the color needs to be fixed.
Visible 2 problems here: 1. "3 vendors 12%" is black text on dark blue background, so hardly readable 2. "4 vendors 6%" doesn't fit nice in pie, so better be out Here, font color is black in LO, but it's also black in MSO. I don't see that MSO has Automatic color for font, just for label fill. So this seems like a problem of label position, not of color. I'll confirm like that. Position was different in LO 4.0, with some labels out. From 4.1 all is inside. I wouldn't call this regression, but bibisect would be useful. Easy to move, so minor issue.

ouch, I overwrote Timur's comment.

Created attachment 161574 [details] The example file in PP and Impress master Label placement looks better since bug #133376 was fixed yesterday. It's not exactly the same since these positions are calculated at runtime.
As noted in Comment 11, PPTX attachment 158424 [details] with chart looks good now in LO so that would be WFM. Positions are not not exactly the same as in MSO, but never mind, it's not worth a bug and this is also clear and readable. This bug turned out to be about positions and another one opened for colors. So let's close this one and keep for colors. QA note: I see in some bugs that reporters are advised to split even similar issues like label position and size but I'm not in favor of that, it's too many bugs for no value. While to split different issues is required, for similar interdependent ones I prefer to keep a single bug until something happens, a fix or change.
