Smooth & Differentiate
This functions needs an effective smooth width as parameter. This is a measure for the intensity of smoothing which will also be implemented for differentiation.

The Find Int button calculates a interval which produces a good result and does not damage the spectrum.

The three Execute  buttons starts the different calculations: Least Square Smooth, FFT Smooth and Differentiation.

The Result Mode radio buttons instructs SciPlot what to do with the results of these manipulations: Overwrite the input buffer or create a new one.

For more information look up in the documentations which are mentioned in the Sources help file.

FFT (Fast Fourier Transfom)
This function makes a Fast Fourier Transform for all selected buffers. For more information look up in the documentations which are mentioned in the Sources help file.

The Result Mode radio buttons instructs SciPlot what to do with the results of these manipulations: Overwrite the input buffer or create a new one.

Linear Regression
This function calculates the linear regression between the X min and X max value by using the following functions.

y  	=   A + Bx
	
B  	=   (n*Sxy - Sx*Sy)  ¤ (n*Sx2 - (Sx)2)
	
A   	=   (Sy - B*Sx)  ¤ n 

r    	=   (n*Sxy-Sx*Sy)  ¤ (Ö((n*Sx2-(Sx)2)  * (n*Sy2-(Sy)2)))
