Mixing bars and plots is cool, here is a quick example of a graph (I can now save and embed etc) of the cpu temperature of a Pi installed at a site where the PV inverter is overheating and cooking everything in the plant room including my monitor, so it’s something I check frequently until they fix the overheating.
It would be nice to have some bar width control once we start playing with daily totals etc, The “fill” box isn’t utilized with bars, perhaps that could be also toggle “filling” the report period (not quite 100%, perhaps 90% to provide gaps) to toggle “line bars” or fill out to “interval bars” eg 1 day or 1 hour for the job at hand?
