Orion TI-84 Plus Talking Graphing Calculator User Guide
8. Press the playback key combo (SHIFT + PREF) to hear the Sonograph
feature for the Graph screen.
Tones are generated by the Sonograph feature depending on the bandwidth. In
Example 1, the Sonograph feature generates tones for all six points in the
following ways:
•
Full screen bandwidth—generates sound for all six stat plot points
•
Half screen bandwidth—band 1 plays 4 points
•
Half screen bandwidth—band center plays 3 points
•
Half screen bandwidth—band 2 plays no points
So in the statistical graph for Example 1, most of the points are trending to the
top of the stats graph.
To use variable band location, press the TI-84 arrow keys (not the Orion arrow
keys) until you find a location on which you want to center the sweep. After you
have selected your location, press the Orion Home key. This will move the band
to the calculator cursor. You can then select a smaller band like one-forth or one-
eighth to get a good estimate of the number of points in that sweep region.
After you have chosen the bandwidth, press the Graph key. Doing this removes
the calculator cursor from the graph screen. To hear the Sonograph of the
selected bandwidth, press the Orion Shift key and select Playback.
