• This chapter contains a number of graph screen shots. In each case, new
data values were input in order to highlight the particular characteristics of
the graph being drawn. Note that when you try to draw a similar graph, the
unit uses data values that you have input using the List function. Because
of this, the graphs that appear on the screen when you perform a graphing
operation will probably differ somewhat from those shown in this manual.
