The AP (Action Priority) risk matrix extends the functionality provided by the SOX risk matrix.
The matrices visualize the value assignments for two (dependent) variables as a function of the third (independent) variable. This third variable (left to right, D, O, and S, respectively) can be manipulated using the slider provided to the left of the relevant matrix.
Notice that if you select (click) a square if any one matrix (in this example, the leftmost one) depending on the position of the slider the corresponding rank and file will be highlighted in the other matrices.
