Host graph with ext. graph

Is it possible to create a host graph window with an exteriour subwindow graph? Analog to panels.
Or can you simply attach one graph window to another?

Any ideas?

Thanks

What do you want to achieve with that? If you want two graphs to follow each other you could also write a hook function (SetWindow) and act on the 'moved' action, dragging the other window along.
That's exactly what I needed!
The goal was just to attach two graph windows belonging together and make them move together, the main graph window and an extra information graph window which can be opened when it's needed.

Mui thanx chozo
I can tell you from experience that writing a hook function that will move one graph when the other is moved will be fraught with difficulty.

There is no such thing as an "external graph", but you could create an external panel, and make the second graph a subwindow in the external panel. Then you leave the hard part up to Igor's internal code. Copy this recreation macro into your Procedure window:
Window Graph0() : Graph
    PauseUpdate; Silent 1       // building window...
    Display /W=(106,120,501,328) junk
    NewPanel/HOST=#/EXT=0/W=(0,0,390,204)
    ModifyPanel fixedSize=0
    Display/W=(92,51,277,156)/FG=(FL,FT,FR,FB)/HOST=#  junk2
    RenameWindow #,G0
    SetActiveSubwindow ##
    RenameWindow #,P0
    SetActiveSubwindow ##
EndMacro

Then execute these commands:
make junk=sqrt(x)
make junk2=gnoise(1)
graph0()
