If the data set and regression line are not ideally positioned, Press Vand select Autoscale. Autoscale can be relied upon to give a good starting scale which can then be adjusted later in the Plot Setup view.

Tracing a scatter	The figures below the plot
plot	indicate that the cursor is
	at the second data point of
	S1, at ((1, 920). Press>to

	point and display
	information about it.
Tracing a curve	If the regression line is not showing, tap		. The
	coordinates of the tracer cursor are shown at the bottom
	of the screen. (If they are not visible, tap		.)
	PressYto see the
	equation of the
	regression line in

	If the equation is too wide
	for the screen, select it
	and press	.
	The example above shows that the slope of the regression
	line (m) is 425.875 and the y-intercept (b) is 376.25.
Tracing order	While >and <move the cursor along a fit or from

the scatter plot or fit you wish to trace. For each active analysis (S1–S5), the tracing order is the scatter plot first and the fit second. So if both S1 and S2 are active, the tracer is by default on the S1 scatter plot when you press P. Press \to trace the S1 fit. At this point, press = to return to the S1 scatter plot or \again to trace the S2 scatter plot. Press \a third time to trace the S2 fit. If you
