Use to randomly offset (jitter) points to reveal overlapping points on a scatterplot or matrix plot. Because a connect line passes through the points, Minitab adjusts the line when the points are offset.
Add jitter to direction: Check to offset points so they do not overlap.
X: Type a number from 0 to 1 to specify the amount of jitter in the x-direction.
Y: Type a number from 0 to 1 to specify the amount of jitter in the y-direction.
