In this box can you chose between three pre-set view angles:

• End view: shows the event as seen from the end of the detector. In this case the beam pipe goes into the picture.
• Side view: shows the event as seen from the side of the detector. In this case the beam pipe goes from left to right in the picture.
• Reset: same as End view plus that the magnification is set so that all tracks are visible on the screen.
