--------------------------------------------

             Summary: Python interpreter - add support for AngularDisplay system
                 Key: ZEPPELIN-1361
                 URL: https://issues.apache.org/jira/browse/ZEPPELIN-1361
             Project: Zeppelin
          Issue Type: Improvement
          Components: python-interpreter
            Reporter: Alexander Bezzubov
             Fix For: 0.7.0


As discussed on mailing list dev@z.a.o subj "improving matplotlib integration in zeppelin" - in order to complete ZEPPELIN-1344 and give ability for one Python paragraph to update content in another one - we can use AngularDisplay system, same as in Apache Spark interpreter.


{code}
So without rerun another paragraph, it's possible to update result of a
paragraph from another.
Any interpreter can get AngularObjectRegistry[3] from InterpreterContext
[4], and AngularObjectRegistry allows create object / add event hook to
communicate with front-end.
