By the knowing how one heaphone graph looks like you can understand the character of the sound. You just need to understand what character do you prefer and then it's way easier to find headphones or iems which most likely fit you.
But graph won't tell you anything about the technical abilities of headphones. So you can't trust the graph and only the graph.
