how to customize the graphical summary view of the survey list

Hi, I created a survey list with a number of open questions. The out-of-box graphical summary view, however, list all questions by default.

This means one bar for every single answer of each open question because most of those answers are expected to be unique.. I tried using Javascript trick to hide certain questions, but there is simply no identifier I can use for each question block..

Is there any way I can choose what questions to present in the graphical view or any other workaround..

Thanks in advance
