Github user Leemoonsoo commented on the issue: https://github.com/apache/zeppelin/pull/2098 @1ambda Great work!!! Looks great to me! I think it's worth to move usages and examples in this PR description under `/docs`. Where do you think this information can be placed? We didn't have any unittest for pivot transformation. So it was hard to improve / change without any side effects. So having some basic unittest for advanced transformation will help other people add and improve the feature much faster.
