In the Time Series Plot dialog box, complete the following steps to specify the data for your graph. If your data are arranged differently than described below, go to Choose a time series plot.
A technician tracks the number of parts that are produced on two different machines each day. The technician records the number of parts in the Parts column and identifies the machine that made the parts in the Machine column. The Y variable is Parts and the group variable is Machine. The technician enters each date only once in the Date labels column to use as the time scale labels.
Because data for both machines was collected over the same period of time, the technician chooses Start all at the same time. The graph shows the number of parts that were produced on each machine each day.
The Time scale labels column must contain only one label value for each interval on the x-axis.
A manager tracks the number of calls that sales representatives receive during two stages of an advertising campaign. Each day, the manager records the number of calls in the Calls column and identifies the stage of the campaign in the Stage column. The Y variable is Calls and the group variable is Stage. The manager also enters the dates in the Date labels column to use as the time scale labels.
Because all of the stage 1 data was collected before the stage 2 data, the manager chooses Plot in consecutive stages. The graph shows that the number of calls that were received each day during both phases of the campaign.
