I was wondering if there was a way to compare the two data sets I have below represented by the graphs. I created this random path between points (1,1) and (10,10) (the orange line) . Through some other things, I was able to get a line that is similarly shaped to orange one. The data is represented by the blue line. Ignoring the rotation for now, is there a mathmateical way to disern the similarity in the trend in the data or the shape of the lines?
