I m adding an interval variable to a dashboard to allow averaging some prometheus time series over an interval to get cleaner looking graphs. But I want to leave in the base sample rate (15s) so the graph can be viewed without averaging.
However, some graphs use rate() which gives no data for the base sample rate.
How can I share $interval for all time series in the dashboard, but force graphs using rate() to use a minimum interval (e.g., 1m) ? Is there something I can add to the query like max($interval,1m)
