Four in one: Choose to display a layout of a histogram of residuals, a normal plot of residuals, a plot of residuals versus fits, and a plot of residuals versus order.

Residuals versus the variables: Enter one or more columns containing the variables against which you want to plot the residuals. Minitab displays a separate graph for each column.
