Removing Oscillation in Curve

  1. Dec 25, 2011 #1
    I want to remove the oscillation from the curve

    In one of the variable i have oscillation values and i want to take avg of them so that i can plot the straight line

    e.g.

    X Y
    100 80
    110 20
    120 70
    130 19
    140 84
    120 26

    I want to post process my data to look something like this
    105 60
    115 45
    125 45.5

    thus i can plot the average of the oscialltion

    I can make average of whole data as oscillations are present in some part of the data and i want to do to selective avergaing of the data

    can anyone help me with this? I am using Origin for plotting the graph

    What you're describing sounds like interpolation (Origin will probably have facilities to do this but I don't know the details). Maybe try splines or B-splines.
