Apple Newton Works Graphing Calculator - Manual (Page 32)

If xScl or yScl are set to values that would generate too few or too many tick marks on
the graph window, their default values are used.
For more information on these variables, see “Graph and Table Variables” in
the section “Using Variables” in Chapter 2.
Viewing a point on the graph
Tapping a curve marks that point with a box and displays the (x,y) values of that
point. Use the left and right arrow keys on your keyboard to move the box to the left
and right, respectively. The box will follow the curve of the graph.
To view the (x,y) values of a point that’s not on a curve, tap the point. An X appears
and the (x,y) values of that point are displayed.
Hint: If you have problems tapping on a curve, tap above (or below) the curve, then
press the arrow keys on your keyboard to move the point in small increments to the
curve. When it reaches the curve, the X changes to a box.
If you have multiple graphs plotted, you can use the Tab key on your keyboard to
move the point between lines.
