I have seen lots of request regarding labels for tables, cross tables ... and I vote positively for these requests.
I would appreciate to have a label orientation between vertical and horizontal, ideally we could choose 30°, 45° or 60°.
it will increase a lot the way to read these visualizations.
Would be great to have slanted labels on the axes that is available in other BI tools and excel. It will be easy to read when there are long labels and too many data points.
