Percentage of choices

I have a view which captures the results of a survey.In this view I will display the Question Number,Question and its corresponding answers given by the survey participants.Now if the question type is radio button,I want to add another column which will tell the percentage of each of the Options.For eg the option is YES and NO,What percentage have answered YES and What Percentage have answered NO.

I used the Total (Percentage of Parent category) in the column property,but it gives like the following.What percentage of ppl have answered each question,What percentage of ppl answered the survey and then the what percentage of ppl answered each of the Options.But I want to display only the last part.i.e What percentage of ppl have answered each of the options.For eg how many percentage of yes and how many NO.How do I do that?Kindly help me.

You need to create a view where the first categorised, percentaged, column is the Column “Answered Yes or No”
