Excel won't do this directly. You can make a new set of y values (y') using a function that translates your original y to y'. This function would map your values such as 0 to 0, 16 to 1, 70 to 2, 200 to 3 and so on. You'd have to decide what function to use for the interior values such as y = 8 to y'=0.5, (linear) and maybe logarithmic between y= 2000 and 30,000. Plot these new values instead of your originals. Then hand jam your own axis labels. I do this a lot for gaussian axes, probabilities and other inconvenient things.
