• Yes! If you notice something in a Data Viewer graph, you can make a note of it to document the irregularity. At the top of the graph is a "notes" option, add a new note by clicking on the plus button. Record the date, time and description and the note will stick itself onto the graph where you and other co-workers can see it. You will also be able to see any notes that have been made under the Events section of the top menu bar.
