Data options for T Chart

Specify whether to include or exclude rows from the control chart.

All rows/No rows

Include or exclude all rows.

Rows that match

Include or exclude rows that match specified conditions. Click Condition to enter the conditional expression.

Brushed rows

Include or exclude all brushed rows.

Row numbers

List the rows to include or exclude. Use a colon (:) to denote an inclusive range. For example, enter 1 4 6:10 to signify the rows 1, 4, 6, 7, 8, 9, and 10.

Leave a space in the graph for the points that you exclude. Minitab treats these values as missing values in the calculations, which affects the estimates of the control limits.
