You can select which harmonics, 1st to 5th, which you want to see by checking the appropriate checkbox.
The sum of all the harmonics is always shown. It is in white.
If you click the 'See' checkbox you will see the separate harmonics drawn behind the white sum.
The 'Slow' checkbox makes the animation run five times slower for careful study.
