1. example
Modelling \(N\): the number of zettels in my notes as a time series, then it could be a time series:
| Day | total zettels |
|---|---|
| 0 | 365 |
| 6 | 428 |
| 7 | 437 |
| 8 | 472 |
And so are every other representations of it(list of (day, total zettels) points, or just (365,428,437,472), assuming even spacing)
