7.2  Graph Screen Operations 

The sections below describe the Graph screen operations with the Orion TI-84 
Plus. It is important to note that when graphing with the Orion TI-84 Plus, you 
should use the 

Trace mode

, not the Graph mode. The Trace mode cursor 

delineates the graphed equation, while the Graph mode cursor moves freely 
around the graph. The Graph mode currently does not give much helpful 
information in regards to the equation. You can do almost all graphing functions 
in Trace mode. 

7.2.1 

Equations Announcement - Trace Cursor Announcement 

In the Trace mode, equations are announced in the following situations: 

1.  When the Graph screen is entered 
2.  When equations are switched using the Up or Down cursor keys 
3.  If the Expression Off setting (ExprOff) is enabled in the 

Format

 menu, 

only the equation number is announced and not the entire equation. 

7.2.2 

X-Y Coordinates Announcement Cursor 

The Coordinate On setting (

CoordOn

) must be enabled in the 

Format

 screen in 

order for X- and Y-coordinate values of the cursor to be announced as the user 
tracks through the graph. If CoordOn is not enabled coordinate values are not 
announced or visible on the screen. Depending on the Orion setting selected, 
either speech or tone output is provided for the coordinate values. 

7.2.3 

Busy Indicator 

The 

busy indicator

 is the series of short beeps that sound when graph data is 

being plotted on the calculator screen. 

7.2.4 

Complete Equation Playback 

The portion of the graph that is visible on the screen is defined as the complete 
equation. When this feature is enabled, the equation is represented by a 
sequence of tones corresponding to the coordinate values. 

When a graph is being plotted for the first time¸ the complete graph is always 
played by default. The complete visible graph is played whenever there is a 
change in the graph because of changes in various settings, equations, or as a 
result of panning or re-centering the graph. 

Playback can also be engaged through the use of dedicated Orion keys. Please 
refer to the section titled "SonoGraph

TM

" below for more details.
