Github user 1ambda commented on the issue: https://github.com/apache/zeppelin/pull/2098 @AhyoungRyu 1. Hide other buttons when panel is minified  2. Added doc to `docs/development/writingzeppelinvisualization_transformation.md`. It looks like  3. Regarding to popup, i think we can skip it because if parameter is applied or reset, the chart will change according to the options. The chart will remain same only if parameter is not changed at all and user can recognize when he/she does't change parameter. @Leemoonsoo 4. I added many tests to `advanced-transformation-util.test.js`. It covers most cases and many functions. Here is the file. - https://github.com/1ambda/zeppelin/blob/6a0559b18542c60b1211095f7583a71e5fb0c136/zeppelin-web/src/app/tabledata/advanced-transformation-util.test.js
