Use to randomly offset (jitter) points to reveal overlapping points on a scatterplot, matrix plot, or 3D scatterplot. Because project lines extend from the points, Minitab adjusts the project lines 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.
Z: (3D scatterplot only) Type a number from 0 to 1 to specify the amount of jitter in the z-direction.
