Using PROC TIMEPLOT

Working with Time Series Data

Using PROC TIMEPLOT

The TIMEPLOT procedure plots time series data vertically on the page instead of horizontally across the page as the PLOT procedure does. PROC TIMEPLOT can also print the data values as well as plot them.

The following statements use the TIMEPLOT procedure to plot CPI in the USCPI data set. Only the last 14 observations are included in this example. The plot is shown in Figure 2.19.

   proc timeplot data=uscpi;
      plot cpi;
      id date;
      where date >= '1jun90'd;
   run;

                                                                                
                                                                                
                                                                                
   date        cpi      min                                                  max
