----------------------------------
Summary: Grouping in pie chart isn't accurate
Key: ZEPPELIN-2237
URL: https://issues.apache.org/jira/browse/ZEPPELIN-2237
Project: Zeppelin
Issue Type: Bug
Components: front-end
Affects Versions: 0.7.0
Reporter: Sravan S
While I was verifying ZEPPELIN-1889, I tried grouping with pie chart, when I
tried grouped data, I think, it's only displaying information from the first
group
* Use bank data from example spark job that comes with Zeppelin.
* Wrote an sql query: select * from bank limit 100;
* In the visualization settings, select pie chart
* Set- key: marital, groups: education, value: avg(balance)
Results displayed in graph:
* Divorced: 61% 487
* Married: 50% 399
This is statistically correct, I guess, because, there is one more result:
'single: -11% -91', which cannot be displayed on a pie chart
But the chart only displays data from people who completed only primary
education, where as it should display results from people with other
educational qualifications
