Hello Everyone , I am new to lab-view hence would need a little assistance in one of the problem i am having right now . My problem statement is : How to calculate Polynomial fit from Waveform graph data ? do i need to convert the waveform data to Graph XY and then use the built-in Polynomial Fit vi to calculate the fitting ? Detail : My problem is that i have waveform graph , i am calculating the peaks and valley but due to noise , my detection of valley and peaks is sometimes not accurate , hence to smoothen the graph i need to apply Polynomial fit . If anyone can help me in this , i will be very grateful . Thank-you in advance

Hi Omar, have you seen Lynn's suggestion above? You already have the Y values (your array). Now you need to build the X array the very same way as shown, only replacing the dt value with your point-to-point spacing. Somewhere in your code you know that value as you have a X axis shown in milliseconds...
