Note: If you make a change
on the active Y= Editor
(redefine a function, change
a style, etc.), that change is
not reflected on the inactive

Independent graph-related applications (Y= Editor, Graph screen,
etc.) can be displayed on both sides of the screen at the same time.
Non-graph-related applications (Home screen, Data/Matrix Editor,
etc.) are shared and can be displayed on only one side at a time.
Even in two-graph mode, there is actually only one Y= Editor, which
maintains a single function list for each
However, if both sides use the same graphing mode, each side can
select different functions from that single list.

When both sides use
different graphing modes,
each side shows a

When both sides use

each side shows the
