WTH - History view. Multiple entities overlay and filter options

There have been quite a few times, I’ve wanted to just simply check back on the History of some entities.

Typically if the entity is a different Unit the History section creates multiple charts. It would be nice if there was the option to overlay the data to combine (and ensure 2 different colours were used). You can do this on dashboards using some chart cards, but for quikcly checking a few things it would be nice to have a few extra options in the History view.

1 - Entity/area/label etc colours
2 - Merge charts (up to 2-3 sources so you could have the Y axis show multiple data levels ie Watts, Litres, etc.
3 - Scale adjuster option per entity.

For example on this. I’d like to have overlaid them easily all together. Amplified/multiplier for the water flow sensor to a higher scale to make it jump out/stand out more. Change the Boiler current power and water use colours as they match. And overlaid them all.

I know you can do the overlays by using another chart tool, but there’s been a fair few times i just wished the History pane had a few extra customisation options as it’s great for quickly picking and selecting sources of data to cross check.
