Graphs: Some way to zoom or expand them

[johnrs]

The graphs are great, but only for an overview of a week. There are many times when I've made a change, or am troubleshooting a problem, that I would like to be able to zoom in.

Actually, a 3 button selection would suffice for most of my cases: 1 wk (as is now), 1 day, and 1hr.

Rather than bloat the base image of the embedded software, maybe it'd be possible to scrape the json output page and use a separate system to graph, like InfluxDB/Prometheus + Grafana.

Not the 1st person to ask for Prometheus, added #101

101 will solve this
