A couple of examples of this chart follow for different courses. In the first
example, for a MOOC, you see enrollment climb fairly steadily over a period of
several months. The markers begin with two "student" enrollments (almost
certainly the course creator and another course team member) on the day the
several months. The markers begin with four enrollments (almost
certainly the course creator and other course team members) on the day the
course was created in Studio.

The chart does reveal several periods when the rate of new enrollments
The chart reveals different time periods when the rate of new enrollments
increased rapidly, or "spiked" (circled). The team for this course might have
the contextual knowledge to correlate those periods with marketing efforts or
automated enrollment events, or might want to research possible explanations.
After the final spike, which coincided with the course start date on 17
September, enrollment continued to increase.
After the first spike, which coincided with the course start date on 15 April,
enrollment continued to increase and an additional spike occurred over a month

Knowing the context of how your course is set up, this pattern might indicate
when the learner reached the first homework assignment. Or, it might indicate
that the learner completed all of the ungraded practice questions and the
midterm on one day.
that the learner completed the first homework assignment in your self-paced
course and then, after some weeks off, completed the second homework
assignment. Or, it might indicate that the learner started your
instructor-paced course on schedule, but is now rushing to complete the
remaining graded assignments before the end of the course.
