1. Considering 'grouping' is 'true' by default - my columns are displayed side by side instead of overlaying each other. Which is logical.
2. Considering my first series ('Ben') has 4 points for same x value - those columns are displayed overlaying each other. Which is logical.
3. Considering 'centerInCategory' is set to 'true' my groups two and three are perfectly centered and have no empty gaps despite second group doesn't have points for several x values. Which is logical.
Every single statement independently is logical. What is not logical is the combination of the three, which you can see in first group.
I would expect either
a) repeating x value columns to be displayed side by side, like all other columns.
b) displaying recurring x value columns as they are (overlaying each other), but not leaving that weird gap
Can you please explain me this behavior?
