Measurements are not to scale. Choose between experiment and results to view either from the list at the bottom left. When results are displayed, moving the mouse near the x-axis shows the alignment of individual phasors (white) and the resultant phasor (yellow). The intensity in the sidebands is exaggerated to make them visible. You can increase, decrease the scale on the y axis by double clicking with right/left mouse buttons. You can view the experimental arrangement from different perspectives by dragging the mouse, but I guess this option is best unused. You can also shift the arrangement by double clicking.
