The simple scatterplot dialog box allows you to choose which variables you would like plotted
and on which axes these variables will fall.  In the define scatterplot dialog box use the cursor keys to select the variable you want.  When you have made 
your selection, type Tab until the the arrow key is highlighted of the axis on which you would like to place the
variable.  When you have chosen all the variables that you want included in your scatterplot, type Tab until the
"Ok" button is selected, then type Enter.

You may create the same scatterplot in SPSS by using the following syntax:

GRAPH
  /SCATTERPLOT(BIVAR)=salbegin WITH salary
  /MISSING=LISTWISE .

To open a syntax window to use the above syntax, type Alt+F, N, and S.
