How to add space between category bars - XY Chart

What is the method to add space between category bars in the perspective XY chart?

When I render as a column I see there is a break property on the x axis but I cannot figure out what text should be put in there for start and end category.

Each category (site) has 3 bars, I just want to put space between them so it is clearer to see.

It would be nice if this happened by default.



I fixed this by adding blanks in the list comprehension from the source dataset tag and then adding 2 additional series one before and one after the actual 3 columns I want with their labels hidden from the legend.

Not sure if this is the best way to do it but it works.
