TI-83 Plus Statistics 338
Using the Stat List Editor When Formula-Generated Lists Are
Displayed
When you edit an element of a list referenced in an attached formula, the
TI-83 Plus updates the corresponding element in the list to which the
formula is attached (Chapter 11).
When a list with a formula attached is displayed in the stat list editor and
you edit or enter elements of another displayed list, then the
TI-83 Plus
takes slightly longer to accept each edit or entry than when no lists with
formulas attached are in view.
Tip: To speed editing time, scroll horizontally until no lists with formulas are
displayed, or rearrange the stat list editor so that no lists with formulas are
displayed.
