[GitHub] [incubator-superset] lctdulac opened a new issue #11953: Missing data (null) in Time Series Table when no filter applied | Not a data issue from our side

URL: https://github.com/apache/incubator-superset/issues/11953


   Hi SuperSet community.
   
   We've been encountering an UI issue with SuperSet when plotting Time Series table. Some datapoints are missing from the graphs and showing ''nulls''. However, the weird thing is, when filtering the data in the dashboard to display only the rows where we witness the issue, those data points appear correctly.
   
   ### Expected results
   
   We except the time series to be plotted without these missing data points (nulls) as there are no nulls in the data.
   
   ### Actual results
   
   Some random nulls appear in the chart though there are data to display.
   When filtering the data, the bug disappears. 
   
   #### Screenshots
   
   **Without filtering :**

   **After filtering to only the rows displayed above:**

   #### How to reproduce the bug
   
   1. Create Time Series table.
   2. Add the time series table to a dashboard.
   3. Filter down on the column used to group by in the time series table.
   4. Compare
   
   ### Environment
   
   The table used for the time series table is (Rows 166,645 | Cols 42) queried using Presto SQL Engine.
   We are aggregating on a VARCHAR column and the data plotted is of type BIGINT.
   
   - superset version: 0.37.2
   - python version: 3.6.12
   
   ### Additional context
   
   The dashboard is very big (close to the size limit).
