Line chart and date range

[Anonymous]

Hi,

I'm trying to make a Vizlib line chart for my forecasting model. But as you see below, as soon as the future dates begins, Actual values hits zero.

How can I make a set analysis date range only for Actual values, thus I only get a range of dates where I also have records.

My code

Forecast = Sum({<hovedbranche_kode={$(vValgtBranche)}>}yhat)

Actual values = Sum({<hovedbranche_kode={$(vValgtBranche)}>}[Brancheomsætning])

I have records until 01/08/2018.

Thanks in advance!
