I just downloaded 1.14.5 and it seems to work when using a setting of minSlices higher than the number of slices in the pie as our initial question stated.
Like when the setting is 9 and I have 8 slices - all 8 slices are shown (no others slice).
However when I set the setting to 8, I get in the same example 5 slices and the others slice is not there so the other three slices are lost and nowhere to be seen.
Here I'd expect either that all 8 slices should be displayed ( sort of minOrEqualSlices ), or instead show 7 slices and 1 in the Others. I prefer the first option but second is fine as well.
In either case I don't think any data should be lost.
