See also: Add Polynomial Fit FB
The Polynomial Fit FB finds a concatenated series of Polynomials (5th order) that are approximately equal to the data at its inputconnector. After you do a PolynomialFit, you can: •Transfer Polynomials directly to MotionDesigner as a new Motion nametab. •Connect a wire from the outputconnector of the PolynomialFit FB to the inputconnector of a different FB. •Export the motionvalues that you calculate as a textfile. •Export the values for position, velocity, and acceleration at the beginning and end of each polynomial segment as a CSV file. •Export the polynomials segments in a format suitable for the SchneiderElectric® EPAS4 servocontroller. 
To open the PolynomialFit dialog

The PolynomialFit dialog is now open.
PolynomialFit FB dialog/interface. 

The PolynomialFit dialog:

Acquire and Save Results toolbar 

The toolbar buttons are:

Number of Fitted Polynomials in Fit (readonly) The number of Polynomials in the numerical solution. See also: Maximum Polynomial Count. in the Settings for Polynomial Fitting Algorithms. RMS Position Error, RMS Velocity Error, RMS Acceleration Error (readonly). They give the RMS (Root, Mean, Square) error for each motionderivative between the PolynomialFit and the data at the inputconnector as a percentage. 
Parameters to enter before you click Fit Polynomials to Data (button in the Acquire and Save toolbar, above)

The toolbar buttons are:

Graph plot color scheme for •original, or input, data •fitted data calculated from the fitted polynomials •each motionderivative •Cursor  you can click ON a graph of each motionderivative to show a cursor. The XY datavalues of the active cursor is above the graphs.
