If the graph shows how much space is filled when a certain threshold is
used, e.g. it shows how many output-values of that value is used, the red
line should not be the one for version 0.5. Let's say the threshold is 0.
Then the graph at x-value 0 would show zero if the function had no plateaus,
because if it _had_ such plateaus, then space would be filled at threshold
zero. If the function had no plateaus, there would be no (very few)
output-values at zero. Therefore, no space should be filled. My point is:
the graphs must be correct.
