The TIMEPLOT Procedure

Example 4: Superimposing Two Plots

Procedure features:

PROC TIMEPLOT statement options:

MAXDEC=

PLOT statement arguments:

	using two types of plot requests
	OVERLAY
	REF=MEAN(variable(s))
	REVERSE

Data set:

SALES

This example

superimposes two plots on one set of axes
specifies a variable to use as the plotting symbol for one plot and a character to use as the plotting symbol for the other plot
draws a reference line to the mean value of each of the two variables plotted
reverses the labeling of the axis so that the largest value is at the far left of the plot.

Program

options nodate pageno=1 linesize=80 pagesize=60;

proc timeplot data=sales maxdec=0;

   plot stove=seller icebox='R' /

                                  overlay

                                  ref=mean(stove icebox)

                                  reverse;

   label icebox='Refrigerators';
   title 'Weekly Sales of Stoves and Refrigerators';
   title2 'for the';
   title3 'First Six Weeks of the Year';
run;

Output

The column header for the variable Icebox in the listing is the variable's label (Refrigerators). One plot uses the first letter of the value of Seller as the plotting symbol. The other plot uses the letter R.
