5.4. Plot two variables at same time

Follow the steps for Plot Point over time, as described above.
In the Properties tab, turn off DISPL (Magnitude), and turn on variables VEL (Magnitude) and ACCL (Magnitude).
Select the line that says ACCL (Magnitude), causing this row to turn gray.
At the bottom of the Properties tab, change Chart Axes to Bottom-Right.
