@djay Copied from PR #152. Maybe we should fix the definitions. That's how I see it at the moment...
Actual - The value at the end of the line or patch. (Not the axis grid values.)
Current - The current value (not average).
Average - The rolling average.
Relative - In percent.
Absolute - In units.

Your suggest makes sense. The thing is that formatters just take a single value and not two basically "independent" values. So you would have to tell me how to get the value pairs. Or maybe just show the average and the current lines as it is done already in some plots, then both could be shown. No value is shown at the moment and it's also not in the legend (probably all lines should be in the legend)...

Another idea could also be to show the relative and absolute values for more plots similar to the population formatter.

By actual I mean the non averaged value. Thats how I've used it in the code.
although the actuals param I've misused a couple of times. I use it for instance to show future predictions on the vaccine chart. Possible I could change the params around to make that distinction.
I don't think current is a good word for that since it implies the latest date.

Maybe call the values shown on axis last values, similar to what I called it in the code before I removed it.

sure. so what would be good is for the last values to show both the avg value and the actual (non avg) value. so the in example above it would show 47K/39K
