Quick and dirty: take two equal-length vectors of values x and y (such as the "real values" in the question, or simulations thereof). Look at plot(sort(x),sort(y)), plot(x,sample(y)), and plot(sort(x),-sort(-y)) to see the extreme behaviors (high correlation, almost no correlation, high negative correlation).
