Hi fellas!

which is the proper way to create a chart where X are dates (day or month or year) and Y is the aggregation (for example sum… or another formula if posible) of the all values of a device variable in each date/period?

Do I have to have this sum previously calculated by using a Analysis? And save it in a Bucket? Or execute that Analysis on the fly?

because I can’t find out the way to do it with Line Widget or Multiple Axis…

Thank you all!
