Github user Leemoonsoo commented on the issue: https://github.com/apache/zeppelin/pull/2133 I tested a bit more and found some cases. 1. Label rotated when unnecessary  2. Label still overlapping when paragraph width is small  To address these problem, I think rotation/hide should be calculated based on actual chart width and combined width of all labels. Or just providing completely manual (provide option to select normal/rotation/hide) could be alternative. @soralee what do you think? Do you have any other idea?
