title: Prometheus range duration in Range vector w.r.t. Grafana time interval
body: <p>I am using micrometer with prometheus and grafana for dashbaords.
  my prom query is : rate(my_counter[10m])
  Now, My current date is 1-Jun-2020  and I select the past dates in time interval of grafana as 1-Feb-2020 to 4-Mar-2020.
  In this case, the rate function will use only 10 minutes of data w.r.t. 4-Mar-2020 23:59:59.
  Is my understanding correct, if no can someone please explain how does it work?</p>
