Here's is a very simple example:
base1 = WIDGET_BASE(....) ;your main base
...
..
base2 = WIDGET_BASE(....,GROUP_LEADER=base1) ;your auxialliary base that
will ; contain the plotting windows
draw = WIDGET_DRAW(base2,.....) ;your draw widget
...
...
base3 = WIDGET_BASE(....,GROUP_LEADER=base1) ;Another auxialliary base
....
....
;**** in your event handling loop use:
event = WIDGET_EVENT([base1,base2,base3],....)
;**** This will monitor all events coming from the bases including the
plotting ; window in your draw widget. To get the info of which
; base it come from use "event.top". When you destroy base1, the rest will
; follow
This should be a good enough start
Good Luck
