The graph in Fig. 6.11 uses two line graphs to show the students’ overall activities
between April and December. One graph shows the number of users, while the other
graph shows the number of activities in the course. When you hover your cursor over
the graph, the peak’s details are shown. For example, on August 3, the peak of the
activities line, 29 of the course’s students were online, and there were 1189 activities,
thus indicating that, even though only 29 users were active on this date, they were
quite active, with each student accessing 41 learning objects on this date.
This view does not show us which learning objects were accessed, but we know
that the highest number of activities was recorded on August 3 and that course was
accessed regularly from April to the beginning of August.
The area of interest can be zoomed in on as well, as shown in Fig. 6.12.
The activities during this time vary, but the number of users who were accessing the
course appears stable. We can also see that no activities are shown between August and
the end of September but that some activities reappeared in October (Fig. 6.13).
