etr2460 opened a new pull request #9313: Revert "feat: add rolling window support to 'Big Number with Trendline' viz"

   Reverts apache/incubator-superset#9107
   
   This change broke rendering of NULL values in the Big Number with Trendline viz. NULL values now render as 0, which is misleading. I'm reverting as this is a data accuracy bug and is fairly high priority.
   
   Repro steps:
   - Run a query like this in SQL Lab:
   ```
   SELECT *
      FROM (
            VALUES ('2020-02-29',
                    4), ('2020-03-01',
                    1), ('2020-03-02',
                         NULL), ('2020-03-03',
                                 2), ('2020-03-04',
                                 3)) AS t (ds, value)
   ```
   - Explore it and select the big number with trend line viz
   - See 0 instead of NULL in the trendline

   Personally I think we should revert per the guidelines as the pending PR doesn’t have a unit test. We should strive to keep `master` as stable as possible.

   Preset has been discussing this internally, and we believe this is a one-line fix. We think that counter-indicates a revert, and are happy to provide a PR so that we can roll forward here instead of roll back.

   @etr2460 was an effort made to reach out to @mistercrunch or anyone else at Preset to come up with a solution to this bug before issuing a revert?

   I'm working on a unit test for the related PR now. I do not think waiting a small period of time for the fix to become stable is unreasonable. I do think pushing through a revert when engineers responsible for the relevant code are available and responding is a questionable choice. It creates unnecessary friction in the community for only momentary gain.

   A couple questions (note that regardless of fix difficulty/complexity I'm still strongly in favor of reverting first, then re PR-ing with both the original commit and the fix):
   - What is the ETA on the fix?
   - Does the fix include a unit test?
   - How confident are we that the fix will completely resolve the issue?

   As per the revert guidelines, I've informed the original PR author on the revert, provided concise repro steps, and gotten the revert reviewed.
   
   As this is a regression caused by a new feature and not a bug fix, and because this is a pretty severe data accuracy issue, I moved towards reverting the PR vs attempting a fix. A fix can be added to the original commit, unit test added, PR-ed out, and reviewed pretty quickly
