What is the feature which is important? How do the other columns look like? Does "similarity" mean that you have a strong gradient after x=4000? Does it mean the plateau is around 0.7? Does it mean you have a negative peak after the first big incline? There are so many possibilities, we cannot know what's the point here.

What do you mean by most similar? Although one thing is that you can order it in aascending or descending order. You will have most similar together..
