<!-- Answer --> Superset maps DuckDB's `double` (float) columns to a generic "number" type in the histogram chart menu—this is expected and not a bug. Superset groups all numeric types (integers, floats, doubles, decimals) under "number" for chart controls, so there is no separate "float" category in the UI. As long as your column is recognized as "number," it should be eligible for histograms, provided the type string from DuckDB matches what Superset expects (it must start with "float", "double", "decimal", or "numeric") and the column has no nulls [[details](https://github.com/apache/superset/discussions/34717#discussioncomment-14114540)]. If your column isn't accepted for a histogram, try casting it in SQL Lab to a standard numeric type like `BIGINT` or `DECIMAL`, and check if it appears as "number" in the chart controls. You can also run `SELECT typeof(column_name) FROM table LIMIT 1` in SQL Lab to see the exact type string DuckDB emits—if it doesn't start with a recognized pattern, Superset won't accept it for histograms. If you still have trouble, let me know the result of that query for more targeted help. <!-- Dosu Comment Footer --> *To reply, just mention [@dosu](https://go.dosu.dev/dosubot).* --- <sup>How did I do?
