Test History Line Graph Q: How do I view the Test History Line Graph? A: To view the Line Graph, click "History" near the pie chart for each test. If you have "All Students" selected, the line graph will show the class average for each date. If you have a student selected, the points will represent each time that student was tested on that test. See the Help Pages below on: Points Shape of Points Date Ranges Have more questions?
