I'm writing a report and I want to describe some data points A becomes discrepant from data points B when a control parameter increases. I think I have learned a one-word expression for being discrepant from something, but I can't remember it. I think it was like divert or something, but the dictionary says divert has another meaning, not what I intended. Could anyone recommend such a word?
What I want to describe is that the graph is gradually changing from the solid line to the dotted line, as in the figure.
