I have the following table which represents what tasks were done by a given machine minute by minute. the counts (40,50) are showing number of entries in logs. Which chart can be used to illustrate that the machine initially worked on task1 up until 13:08 and eventually started working on task2 from 13:09 ?
| time | task1 | task2 |
|---|---|---|
| 2022-09-08 13:08:00 | 40 | |
| 2022-09-08 13:09:00 | 50 |
