Choose subgroups to display
To see only the most recent subgroups instead of all subgroups, enter the number of subgroups to include in the chart. Minitab still uses all the data to calculate the control limits and the center line.

By default, Minitab displays all subgroups.
- Last

This chart displays only the most recent number of subgroups that you enter. By default, Minitab displays the last 25 subgroups.
Split chart into a series of segments for display purposes
When you have a large number of subgroups or observations, consider splitting your control chart into segments for easier interpretation.
If your chart has stages, Minitab calculates separate control limits and center line estimates for each segment.
This control chart is split into two segments, by stage.
