Dashboarding issue

Hello everyone,

I need help in Dashboarding

I'm working for a manufacturing firm, where i'm having 6 machines that belong to 2 sections.

The End user wants to see daily production in terms of graphs/ charts

End users want graph like this; If they change to section 2 it will show section 2 Machines data

But when i'm trying to do charting i'm getting the graph like this

So i used synchronize section's in the dashboard design part, as a result of this synchronizing process i'm getting chart like this

But Endusers doesn't want to see section1 or section2 data in the graph, so what should i need to do in order to remove section's in the graph
