'Null' value is being displayed as '0' in the data retrieved (Slices).
What's the difference between the 'Null' value being displayed as '0' and an integer column with a '0' value?
Isn't it false reporting?
Is there any background history against this implementation?
Which visualization?
I get this same issue in the table view.
Thanks for your response, You can test it for Table view, histogram etc.
Correct me if I'm wrong, but I believe this issue is fixed with https://github.com/apache/incubator-superset/pull/4358
Are you still seeing the issue on the latest version?
Thanks @jeffreythewang, I have tested this ticket against the mentioned PR and found that this issue seems to be fixed for string type of columns.
But for integer type of columns, the _Null_ values are being displayed as '0'.
This issue is required to be FIXED for all type of columns.

This issue was fixed in 0.27 but is now back in 0.29.rc07
