Plot sales of refrigerators. The plot variable, Icebox, appears in both the listing and the output. POS= provides 50 print positions for the horizontal axis.

proc timeplot data=sales;
   plot icebox / pos=50;

Label the rows in the listing. The values of the ID variables, Month and Week, are used to uniquely identify each row of the listing.

   id month week;

Specify the titles.

   title 'Weekly Sales of Iceboxes';
   title2 'for the';
   title3 'First Six Weeks of the Year';
run;

Output
