Line View Notification

Line View visualizer is different from other visualizers in that it does not open a visualizer window. Instead, it adds the line state signals to the application scrollbar. If you have multiple running monitoring sessions, it displays the line states for the currently active session.

This notification informs you about the location of the Line View visualizer you added to the monitoring session.
