<!-- Answer --> The reason your FLOAT column shows a ? icon (not #) in the chart builder UI is that Superset 5.0.0 uses strict backend regex matching to decide if a column is numeric. Even if SQL Lab shows the type as FLOAT (using SQLAlchemy's mapping), the chart builder relies on the raw type string from DuckDB. If that string isn't an exact match for patterns like ^float, ^double, ^decimal, or ^numeric (for example, if it's DOUBLE PRECISION or DECIMAL(18,4)), Superset doesn't recognize it as numeric and marks it with a ? icon. Only columns recognized as numeric by this logic get the # icon and can be used in numeric-only fields like histograms. This is a backend limitation, not a UI bug, and was relaxed in newer Superset versions to support more type strings. In 5.0.0, the only workaround is to patch the engine spec or upgrade to a newer version where this is fixed.
