Hi Hishfish, If you take a look Clock example [1], you'll see how it creates angular objects and update every seconds from backend, so front-end can be updated accordingly.
After you add your object into AngularObjectRegistry, you can get AngularObject and add watcher [2]. Then any changes of the angular scope variable from front end will trigger your watcher where you can place your backend logics. Hope this helps, Thanks, moon [1] https://github.com/apache/zeppelin/blob/master/zeppelin-examples/zeppelin-example-clock/src/main/java/org/apache/zeppelin/example/app/clock/Clock.java#L72 [2] https://github.com/apache/zeppelin/blob/master/zeppelin-interpreter/src/main/java/org/apache/zeppelin/display/AngularObject.java#L219 On Mon, Mar 20, 2017 at 8:47 AM fish fish <fishfish...@gmail.com> wrote: > Hi Group, > > Recently we are exploring building data analysis application based on > Zeppelin.
