I’m wondering if it is possible to include max/min type representation (vertical line with a ‘T’) at each end showing the max/min for a day?
I’d like to overlay the max/min temperatures onto a daily consumption graph.
If not using EmonCMS, could Grafana do that? Or might I need to learn “R” (stupid name for a product).

I’ve used the “Min/Max daily value” process in my input, which logs to a couple extra feeds:
…which I can then overlay onto my daily charts.

I think I saw a question about what the time period used was. You would hope it was local time and not UTC 
You may already know about this, but if not, here’s one way that’s very fast and easy to get Grafana
to show min/max values, albeit not as part of a bar on a chart.
The Show, As Table, To the Right, Min and Max checkboxes are the pertinent controls.
I run an older version of Grafana. (v5.4.5) This will be different if you’re running a newer version,
but the checkboxes have the same names and do the same thing.
The result looks like this:
The values can be displayed to the right of the graph, as well:
