though I have not the least idea, what for you want to do this (in graphics you will see either 100% or 0%)
you have in the statistics page the option to select the answer IDs.
E.g.
answer ID>39
answer ID<41
will give you the answer ID 40.
So you can select each single answerID and you will get the statistics of this respondent.

Maybe I misunderstood your problem.
In this case please explain.
Volunteers are not paid.
Not because they are worthless, but because they are priceless
