Draws a line of the amplitudes of the harmonics of Fourier transform
vs. frequency.
Frequency

Integral y C
Draws a line in which each point is the discrete integral of all the
preceding points in a data set.

Draws a line of the kinetic energy of a data set. The argument
must be the velocity of the body, and the constant
mass of the body.
Linear =
y C
Draws a line of a linear displacement of a data set. This function is
useful when you want to change the point of origin of a data set.
