When using PingPlotter to monitor long-term connectivity/latency, you sometimes run across a situation where your network was affected by something you know about (power outage, reboot of router, big file download, etc.). These incidents show up in PingPlotter. Also, you may run into a situation that you don't control - but you know what's causing it. You want to take notes about this kind of thing and tie it to your data.

PingPlotter allows you to make notes on your time graph. These notes show up on the graph as triangles, and when you float over them, the notes appear. When you save data as an image from PingPlotter, these notes get attached to the image, along with the times they happened. This is especially valuable when you want to send an image to a network provider and there are events on the data you're sending them that need to be explained. You can mark these on the time graph and when you create the image, the notes will be included.

To create a note, just right-click the lower time-graph at the point you want to create a note and select "Create Comment" from the popup menu. PingPlotter will prompt you for the note, and then draw a red triangle on the lower edge of the time graph. You can float your mouse over this triangle to see the note, or you can right-click on the triangle to edit or delete it.  You can edit or delete an existing comment by right-clicking on the comment.
