Use to evaluate trends in multiple time series as well as each series' contribution to the sum. Minitab can generate calendar values, clock values, or index values for the time scale, or you can use your own column of stamp values. See Time Overview.

The plot below shows the daily production of manufacturing plants at 3 locations over 24 days.

 

The area below each line represents the cumulative total:

·    Top line = Pittsburgh + Philadelphia + Cleveland

·     Middle line = Philadelphia + Cleveland

·     Bottom line = Cleveland

Dialog box items

Series:  Enter one or more columns of time series data. Minitab displays all columns on the same graph.

Tip

You can use Minitab's paneling options to display graphs of different groups side by side on the same page. If your time series has many values, you may want to split data across panels.
