The TIMEPLOT Procedure

Overview

The TIMEPLOT procedure plots one or more variables over time intervals. A listing of variable values accompanies the plot. Although the plot and the listing are similar to those produced by the PLOT and PRINT procedures, PROC TIMEPLOT output has these distinctive features:

The vertical axis always represents the sequence of observations in the data set; thus, if the observations are in order of date or time, the vertical axis represents the passage of time.
The horizontal axis represents the values of the variable that you are examining. Like PROC PLOT, PROC TIMEPLOT can overlay multiple plots on one set of axes so that each line of the plot can contain values for more than one variable.
A plot produced by PROC TIMEPLOT may occupy more than one page.
Each observation appears sequentially on a separate line of the plot; PROC TIMEPLOT does not hide observations as PROC PLOT sometimes does.
The listing of the plotted values may include variables that do not appear in the plot.

Simple Report Created with PROC TIMEPLOT illustrates a simple report that you can produce with PROC TIMEPLOT. This report shows sales of refrigerators for two sales representatives during the first six weeks of the year. The statements that produce the output follow. A DATA step creates the data set SALES.

Simple Report Created with PROC TIMEPLOT

More Complex Report Created with PROC TIMEPLOT is a more complicated report of the same data set that is used to create Simple Report Created with PROC TIMEPLOT . The statements that create this report

create one plot for the sale of refrigerators and one for the sale of stoves
plot sales for both sales representatives on the same line
identify points on the plots by the first letter of the sales representative's last name
control the size of the horizontal axis
control formats and labels.

For an explanation of the program that produces this report, see Showing Multiple Observations on One Line of a Plot .
