Please clarify what exactly doesn't match. Are you sure you understand
the meaning of the numbers ?

It is in the log, it just isn't drawn in your graphs.
You can actually make your graphs wider to see all the data.
Other way around, you can make them smaller to display less.

Well, perhaps you could try for yourself. Modify the width of the
graphs and check if the percentages change.
