How to generate an average in Prometheus

I have two counters. One is a measurement accumulator and another is the count of measurements. How do I generate a range vector average?

I've tried the following but got null results.

rate(my_events{type="sum"}[60s]) / rate(my_events{type="count"}[60s])

I want to generate a vector that I can put into a Grafana graph to plot the average over time.

You're onto the right idea, what you'd do is:

rate(my_events{type="sum"}[60s]) / ignoring(type) rate(my_events{type="count"}[60s])

However the canonical way of exporting and thus using this data is:

rate(my_events_sum[60s]) / rate(my_events_count[60s])

Which you can do with a Summary or Histogram.
