Compass calibration not working

When I try to calibrate the compass on the Pixhawk in the Mission Planner, when I keep it perfectly still, it plots a perfect vertical line on the left side graph. Does anyone know what could be causing this? I know it’s not a blown regulator because I just recieved it and followed Painless360’s tutorial down to the tee. Here’s a picture.

there is something wrong with your compass, I have no idea what.
