hi.

i am trying to change window format.
if i have 10 windows in a workspace, should i change it one by one?
can i select all windows and change format of all at once?

thanks.

What kind of format you are talking about?

Are they the same instrument?

say, i have 10 different instruments on 10 windows,
and want to change all of its background color or x and y axis scale..and things like that.
