Subject: Alertness graphs show nothing
Question
In my SuperMemo, Alertness graphs in SleepChart show nothing or show error messages.
Answer
To see how your alertness changes in the course of the day, you need to first log in your sleep data. Moreover, you need to make repetitions on the days you log your sleep. If you have no sleep data, or sleep blocks are not interspersed with repetition blocks, you will not be able to see your alertness graphs in SuperMemo.
