Interpolation error

I found out that If I have too many periods in defining "Interpolation function" with an external data file, I get some errors in interpolation. As attached.

e.g.,
for 20 period of an arbitrary function the interpolation is reasonably good by choosing nearest neighbour.
But for 100 period of an arbitrary function, the interpolation goes up and down, there is an extra envelope error due to different interpolation method. I guess there is some basic setting problem.


Did anyone has any suggestion?
