**You have to define the frequency, the sample rate (samples/sec), the length
in seconds and the amplitude. The X axis will be interpreted as seconds, so a
frequency of 2 Hz with a sample rate of 20, a length of 1 second and an
amplitude of 1 will produce a plot of 2 sinuses with 21 data points:

** g
****white noise
**You have to define the sample rate, the length in seconds and the
amplitude.

*white noise with the corresponding histogram of Y-values*

** g
****Gauss noise
**You have to define the sample rate, the length in seconds and the
amplitude for 99.7% of the distribution.

*gaussian noise with the corresponding histogram of y-values*

** g
****Gauss curve
**You have to define the center, the peak value, the standard deviation and
the resolution. The width of the peak will be approximately 6 times the standard
deviation.
