EBoisseauSierra opened a new issue #15294:
URL: https://github.com/apache/superset/issues/15294


   I have been able to define custom time grains (e.g. 15-minute time buckets — 
cf. #15037), as per [the `config.py` 
instructions](https://github.com/apache/superset/blob/1.1/superset/config.py#L498-L522):
   
   ```python
   # Define how to compute the custom time buckets
   TIME_GRAIN_ADDON_EXPRESSIONS = {
       'postgresql': {
           'PT6H': "date_trunc('day', {col}) + date_trunc('hour', {col})::int / 
6 * interval '6 h'",
           'PT15M': "date_trunc('hour', {col}) + date_part('minute', 
{col})::int / 15 * interval '15 min'",
       },
   }
   
   # Register these custom time grain
   TIME_GRAIN_ADDONS = {
       "PT6H": "6 hours",
       "PT15M": "15 minutes",
   }
   ```
   
   My custom time grains are then sorted *after* the default time grains:

   ### Expected results
   
   I would expect all time grains to be sorted by increasing duration. In the 
example above:
   
   […]
   * minute
   * 15 minutes
   * hour
   * 6 hours
   * day
   
   […]
   
   ### Actual results
   
   My custom time grains are sorted after any default ones. Their relative 
order is defined by the by `TIME_GRAIN_ADDON_EXPRESSIONS` keys' order, and not 
`TIME_GRAIN_ADDONS`'s ones.
   
   #### How to reproduce the bug
   
   1. Define custom time grain in `superset_config.py`, as above,
   2. Go to Explore / {any Time Series chart}
   3. Click on the Time Grain dropdown menu.
   
   ### Environment
   
   - superset version: `superset 1.1.0`
   
   ### Checklist
   
   - [x] I have checked the superset logs for python stacktraces and included 
it here as text if there are any.
   - [x] I have reproduced the issue with at least the latest released version 
of superset.
   - [x] I have checked the issue tracker for the same issue and I haven't 
found one similar.
