show part of a visual but use last 3 month

[Pikachu-Power]

hi all,

i have the following line chart with forecast last week: 

In a slicer i use last 3 month. So the forecast evaluate the forecast on the basis of the last three month. How can I show only the last 2 weeks of the line chart but evaluate furthermore the last 3 month?

When I change the slicer to the last 2 weeks the forecast changes because it evaluate the data of last week. Or when I use a measure the forecast also changes and use the restrictions in the measure. 

Is it possible to do that?

Thanks.

Hello. I use the built in forecast function.

Is somewhere a documentation how to built it on my own? Would also be interesting to check that.

Hi, @Pikachu-Power 

Sorry, The built-in forecast function in visual will change according to the context(date range), It is by design. Only if you customize values without using built-in forecast function.
