Heatmap using Prometheus Histogram?

I’m loving the new Histogram panel, and it works beautifully with raw data from InfluxDB. I’m starting to look into the Prometheus Histogram datatype, and it seems this could be a good fit for the “pre-bucketed data” option in the Histogram panel.

I’m not sure how I can structure my Prometheus query to satisfy this requirement though:

> Each time series already represents a Y-Axis bucket. The time series name (alias) needs to be a numeric value representing the upper interval for the bucket. Grafana does no bucketing so the bucket size options are hidden.

Any suggestions?

yea, it does not work with Prometheus yet
