Bar chart with repeated X-values

### Description

Not sure if this is considered a bug or feature request.

I want to show a bar (or line) chart with duplicated X-values (labels).

This is actually showing hours on the X-axis, and the scope is the hours of today and tomorrow. I prefer to just show the hours like "00"-"23". So duplicate X-values (labels) will occur.

This currently does not work, as the second occurrence of a given duplicated hour, seems to overwrite the first occurrence.

I do have unique X (time)-related values on each input object. So if one property could be used as the X-value and another as the X-label, that would be really nice. Or some other way to achieve this :)
