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 Chapter 3: Function Graphing 76
