When you create a new viewport, it initially inherits the customization options of the current viewport. For example, if you establish the Filled render style for undeformed plots in the current viewport and then create a new viewport, subsequent undeformed plots in the new viewport will appear in the filled render style. New viewports display the current output database (if any) in the fast plot mode; they do not inherit the plot mode of the current viewport.

After a new viewport has been established, the plot mode and any subsequent customizations are independent of other viewports. Multiple viewports can each be in a separate plot mode; if you use multiple viewports, you must first designate a particular viewport as current to change its display. Customization selections you apply affect only the current viewport. When you designate a viewport as current, the options dialog boxes are refreshed to show the state of options associated with that viewport.
