Charting binary items like switches with fixed perdios

Hey all,

I am creating a combined chart where I want to show energy consumption correlated to presence state. I am using fixed interval charts to show the energy consumption per day. Now I wanted to add in the presence status, which is a switch item and using the min/max function to either show home or away even if I was only out half-day.

The problem I have now is that as soon as I switch from dynamic period visualization to fixed time frame the chart is not showing anything…

Any ideas how to make this work?

Fixed:
