The Y Markers
Y1 and Y2 Fields
The Y1 and Y2 markers are used for rescaling data on the vertical axis.
Assigning values to these fields can be accomplished in either of two ways.
When the field is selected the first time, it turns light blue and operating the
knob will change the Y marker value. If the field is selected a second time, a
pop-up keypad appears and becomes the entry method for the Y-marker
value. The Y1 and Y2 markers may be used to zoom in on data of interest in
the vertical range. To do this, touch the Rescale field, then select "between Y
axis markers." For more information on rescaling data, refer to the "Rescale
Field" section later in this chapter.
