ExprOn, ExprOff
ExprOn
and

when the trace cursor is active. This format setting also applies to stat
plots.
When
ExprOn
is selected, the expression is displayed in the top-left
corner of the graph screen.
When
ExprOff
and
CoordOn
both are selected, the number in the top-right
corner specifies which function is being traced.
