Users often ask if they can have more than one view in their model and show different things, or show the same things differently, in each one.
Hopefully in the future we'll provide this capability directly. But it is already possible now using HubNet with local clients. It's a bit awkward, but it works.
You'll need to be using NetLogo 5.x, not some older version.
Now you've got a second view, identical with the main view.
But identical views are no fun. You want the other views to show something different. The relevant primitives are:
It's especially useful to override the turtle and link variable
hidden?, to make things invisible in one view and visible in another.
Most of the above steps can be done by code in the Code tab. And once you've added the view to the HubNet client, it's saved with the model so you don't need to add it again.
But a few manual steps are necessary. You have to click the Start button after
hubnet-reset and check the view mirroring checkbox.
Show only red turtles, make them bigger, and label them with coordinates:
hubnet-send-override one-of hubnet-clients-list turtles with [color != red] "hidden?" [true] hubnet-send-override one-of hubnet-clients-list turtles "size"  hubnet-send-override one-of hubnet-clients-list turtles "label" [(word pxcor " " pycor)]
