There are many options, have a look at my graph in the huge-apex-post.
I want to trace consumption per day and set it out vs. production with forecast.
tbh, I have not yet found any practical use for the forecast other than making a nice looking graph 
Could you please mark the solution vingerha has provided ?
Would help all others that it is a SOLVED issue and therefore worth to read.
Right now it seems to be still open and I had to read it all instead of clicking the solved button which than pushes his last answert to the TOP and everyone else will know that it is solved.
@vingerha had invested his time to solve it, so now it is your turn to thank him with that solution found button.
Well I would be pleased to do that if there was a SOLVED ICON available
see my earlier post in this thread β¦
****** SOLVED - FINISHED - END OF *********
(what else can I do)
thanks - I was not aware of that and had thought that you could mark that always or move that tag to a better comment as the solution.
Wish you a great chrismas time.
