A scatterplot matrix helps you visualize the correlations between each pair of response variables. The scatterplot matrix is shown by default, and can be hidden or shown by selecting Scatterplot Matrix from the red triangle menu for Multivariate.
When you look for patterns in the scatterplot matrix, you can see the variables cluster into groups based on their correlations. Scatterplot Matrix shows two clusters of correlations: the first two variables (top, left), and the next four (bottom, right).
