The Label radio box is used to select labelling for the samples.

Select: Both to label centroids and samples.

          Samples to show the sample names.

The Plot radio box allows the selection of centroids and samples for plotting.


The axes displayed in the plot are selected using the Plot x Axis, y Axis z Axis drop-down boxes on the Axes to Plot tab. The default is axis 1 and axis 2, which will display the relative positions of the samples using the scores for the two functions with the largest eigenvalues.


In two-dimensional plotting it is also possible to draw a perimeter line around the members of each predefined group.
