Path sequence is represented by colour. Using a rainbow heat scale colour change occurs upon termination of a repeated subsequence, that is, upon the occurrence of a visitation to a previously unvisited path.

From the diagram above we can view the path a student took through a section of a digital media elearning site. He/she visits a range of lecture note material, mostly in sequence (cold colours to the left and warm colours to the right), for Week 2 to Week 9 of a Level 3 module. A typical short spike surf pattern is evident here as the student returns to the module introduction each time to select the next set of lecture notes.
