You can trace along a function using the *>, or*A, key which moves the cursor along the graph. The display also shows the current coordinate position (x, y) of the cursor. Trace mode and the coordinate display are automatically set when a plot is drawn.
Note: Tracing might not appear to exactly follow your plot if the resolution (in Plot Setup view) is set to Faster. This is because RES: FASTER plots in only every other column, whereas tracing always uses every column.
In Function and Sequence Aplets: You can also scroll (move the cursor) left or right beyond the edge of the display window in trace mode, giving you a view of more of the plot.
If there is more than one relation displayed, press *k, or *e, to move between relations.
To jump straight to a value rather than using the Trace function, use the *272_ menu key. Press *272_, then enter a value. Press 2._ to jump to the value.
If the menu labels are not displayed, press 0(18_ first.
•Turn off trace mode by pressing 75$&_.
•Turn on trace mode by pressing 75$&(_.
•To turn the coordinate display off, press 0(18_.
One of the menu key options is =220_. Zooming redraws the plot on a larger or smaller scale. It is a shortcut for changing the Plot Setup.
With the Set Factors option you can specify the factors that determine the extent of zooming, and whether the zoom is centered about the cursor.
Press =220_, select an option, and press 2._. (If =220_ is not displayed, press 0(18_.) Not all =220_ options are available in all aplets.
