Histogram chart empty in case of few equal values


I am using Grafana OSS version v9.3.6 on Ubuntu 22.04.
I noticed a problem while building an histogram chart: in case the underlying query extracts few equal values (example of resultset: one column, two rows with same numeric values: 30), the chart shows no data.
I’d expect instead to see the distribution of such few values, as it is normally the case for more rich datasets.

I’d like to know if this is a known bug ? Is there a way this bug fix can be planned/solved ?

Thank you very much for your help
