k Drawing a Scatter Diagram and  xy  Line Graph
  The following procedure plots a scatter diagram and connects the dots to produce an  xy  line 
graph.
  
  1. From the Main Menu, enter the  Statistics  mode.
  2. Input the data into a list.
  3.  Specify Scatter (scatter diagram) or  
xy Line ( xy  line graph) as the graph type, and then 
execute the graph operation.
  
  Press  A,  J or  !J(QUIT) to return to the List Editor.
  Example  Input the two sets of data shown below. Next, plot the data on a scatter 
diagram and connect the dots to produce an  
xy  line graph.
  
      0.5,  1.2,  2.4,  4.0,  5.2  ( x List) 
    –2.1,  0.3,  1.5,  2.0,  2.4  ( 
y List)
