Override graph resolution

I would like to create a variable by which I can override the resolution of the graph. (I’m using Grafana with influxdb)

By default graphs use the resolution of - i guess - the screen, which is quite high. I know that it is possible to modify the interval with an interval variable, however this only allows specific time intervals that doesn’t take into account the time range, or an ‘auto’ time variable that doesn’t consider the screen resolution.

What I would really like to do is set a scaling factor for the auto calculated interval. Is it possible to do this somehow? I’ve tried everything I can think of and no success so far.
