How can I remove oscillation from a curve using selective averaging?

[samarth]

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.
