[GitHub] [superset] frafra opened a new issue #16832: Time-series Line Chart - Time Grain - does not work if time is not a string
frafra opened a new issue #16832:
URL: https://github.com/apache/superset/issues/16832
"Time-series Line Chart" can show timeseries where the time column is a bigint, but it fails when trying to set the time grain.
### Expected results
It should work.
### Actual results
```
Error: function date_trunc(unknown, bigint) does not exist LINE 1: SELECT DATE_TRUNC('year', year) AS __timestamp, ^ HINT: No function matches the given name and argument types. You might need to add explicit type casts.
```
#### Screenshots
If applicable, add screenshots to help explain your problem.
#### How to reproduce the bug
1. Load default/examples datasets
2. Go to "Games per Genre over time"
3. Set the time grain to "Year"
4. Click "Run"
5. See the error
### Environment
(please complete the following information):
Latest Docker image.
### Checklist
Make sure to follow these steps before submitting your issue - thank you!
- [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.
### Additional context
`date_trunc` is used over the time column, which can be a string or can be an integer-like column. "Time grain" fails if the date column is not a string.

@frafra is it the Echarts time series or the legacy one?

@junlincc how can I determine that? I just selected "Time-series Line Chart", which seems to be one of the basic ones. No add-on installed, just plain Apache Superset.

@junlincc how can I figure that out? I just selected "Time-series Line Chart", which seems to be one of the basic ones. No add-on installed, just plain Apache Superset.
