Chapter 3: Function Graphing 76
AxesOff does not display the axes.
This overrides the
LabelOff/LabelOn format setting.
LabelOff, LabelOn
LabelOff and LabelOn determine whether to display labels for the axes (X and Y), if AxesOn format
is also selected.
ExprOn, ExprOff
ExprOn and ExprOff determine whether to display the Y= expression 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.
Displaying Graphs
Displaying a New Graph
To display the graph of the selected function or functions, press s. TRACE, ZOOM
instructions, and CALC operations display the graph automatically. As the TI-84 Plus plots the
graph, the busy indicator is on. As the graph is plotted, X and Y are updated.
Pausing or Stopping a Graph
While plotting a graph, you can pause or stop graphing.
• Press Í to pause; then press Í to resume.
• Press É to stop; then press s to redraw.
Smart Graph
Smart Graph is a TI-84 Plus feature that redisplays the last graph immediately when you press
s, but only if all graphing factors that would cause replotting have remained the same since
the graph was last displayed.
If you performed any of the following actions since the graph was last displayed, the TI-84 Plus will
replot the graph based on new values when you press s.
• Changed a mode setting that affects graphs
• Changed a function in the current picture
• Selected or deselected a function or stat plot
