             Summary: Piechart rendering issue when coloumn selcted as 'key' is changed
                 Key: ZEPPELIN-2253
                 URL: https://issues.apache.org/jira/browse/ZEPPELIN-2253
             Project: Zeppelin
          Issue Type: Bug
          Components: GUI
    Affects Versions: 0.7.0
         Environment: Chrome 56 Ubuntu
            Reporter: Sravan S


Pie chart isn't rendered properly if we change key(domain) at runtime
Steps to reproduce:

* Create a built in pie chart visualization using an sql table with columns, say Job, Balance and Education.
* Set Job as key and sum(Balance) as values
* Delete key Job
* Set column Education as key
* Notice the empty spaces in chart

Paragraph used:
{noformat}
%sql
select * from bank
limit 20
{noformat}
