In this example, you will use the initial dialog box to 
customize the Data Prompter before importing a data file that contains 
scattered data values for two variables. The organization of the file 
is: #!CForestGreen #!N #!N  #!F-adobe-courier-bold-r-normal--18*   #!N x, y, data1, data2 #!N 
x, y, data1, data2 #!N . . . #!EF #!N #!N 
#!EC where x, y define the positions (or locations) of the 
data. (See also "For Future Reference" later in this example.) #!N 
#!I0 #!N  #!F-adobe-times-medium-r-normal--18*   #!N #!N #!I30 #!N 1. First, invoke the 
Data Prompter (as in Example 1, Step 1). When the initial 
dialog box appears, click on the  #!F-adobe-times-bold-r-normal--18*   Grid or Scattered File 
#!EF button for scattered data. Then click on the  #!F-adobe-times-bold-r-normal--18*   Grid 
Type #!EF button for scattered data (farthest right). #!N #!I30 #!N 
2. Use a stepper button to set  #!F-adobe-times-bold-r-normal--18*   Number of variables 
#!EF to "2." #!N #!I30 #!N 3. The data positions are 
specified in the data file itself, so activate the  #!F-adobe-times-bold-r-normal--18*   Positions 
in data file #!EF toggle. #!N #!I30 #!N 4. The data 
positions are 2-dimensional (x,y), so use a stepper button to set 
 #!F-adobe-times-bold-r-normal--18*   Dimension #!EF to "2." #!N #!I30 #!N 5. Verify that 
the  #!F-adobe-times-bold-r-normal--18*   Single time step #!EF toggle is activated. #!N #!I30 
#!N 6. Set  #!F-adobe-times-bold-r-normal--18*   Data Organization #!EF to  #!F-adobe-times-bold-r-normal--18*   Columnar #!EF 
. #!N #!I30 #!N 7. Click on  #!F-adobe-times-bold-r-normal--18*   Describe Data #!EF 
. The simplified prompter window appears. #!N #!I30 #!N 8. Position 
the mouse cursor in the  #!F-adobe-times-bold-r-normal--18*   Data file #!EF field at 
the top left and type in the path name /usr/lpp/dx/samples/tutorial/spreadsheet.data. #!N 
#!N You can view the file by choosing  #!F-adobe-times-bold-r-normal--18*   Browser #!EF 
(as in Example 1). #!N #!I30 #!N 9. There is no 
header in this file. Set  #!F-adobe-times-bold-r-normal--18*   # of Points #!EF to 
"49." #!N #!I30 #!N 10. To save the header file you 
have defined, select  #!F-adobe-times-bold-r-normal--18*   Save As... #!EF in the  #!F-adobe-times-bold-r-normal--18*   File 
#!EF pull-down menu. Save the file under any name you choose. 
#!N #!I30 #!N 11. The  #!F-adobe-times-bold-r-normal--18*   Test Import #!EF and  #!F-adobe-times-bold-r-normal--18*   
Visualize Data #!EF buttons in the initial Data Prompter window are 
now enabled. Choose  #!F-adobe-times-bold-r-normal--18*   Visualize Data #!EF to see a visualization 
of this scattered data. #!N #!I0 #!N #!EF #!N #!N #!N

It is important to note that the top-to-bottom order of items 
in the  #!F-adobe-times-bold-r-normal--18*   Field list #!EF (right side of window) is 
the same as the left-to-right order of items in the data 
file itself: #!N #!N #!CForestGreen #!N  #!F-adobe-courier-bold-r-normal--18*   #!N  #!F-adobe-times-bold-r-normal--18*   locations #!EF 
x, y #!N  #!F-adobe-times-bold-r-normal--18*   Field0 #!EF data1 #!N  #!F-adobe-times-bold-r-normal--18*   Field1 #!EF 
data2 #!N  #!F-adobe-times-bold-r-normal--18*   ... #!EF  #!F-adobe-times-bold-r-normal--18*   ... #!EF #!EF #!N #!N 
#!EC #!N #!N ( "locations" is a General Array reserved word 
used to indicate when numbers in a data file are to 
be interpreted as "positions"). #!N #!N The order of the field 
list can be changed (with the  #!F-adobe-times-bold-r-normal--18*   Move field #!EF stepper 
buttons) to agree with the order in the data file. #!N 
#!N If other information (e.g., descriptive text) is interspersed among the 
data values, you must use the layout options available in the 
full Data Prompter (see  #!Ldprlayt,dxall168 s Layout  #!EL  and  #!Llaytkwd,dxall149 h layout  #!EL  ). #!N #!N #!EC
