A friend of mine recently showed me a scientific plot. It is essentially a function that goes up and down like a Sin wave or a Cosine wave. He described it as a wiggle in the data. But this "wiggle" is not moving. All definitions I have seen define wiggle as a kind of movement/motion. This function is certainly not wiggling but can this static wave-like pattern be called a wiggle? Is there a wiggle in the data?
