Thanks!
I hate to say, but that options pie chart makes no sense. That's the wrong type of chart. The options are not mutually exclusive and will never add up to 100%. 60% had no options - but they don't appear in that chart.
A pie chart is appropriate for colors, models, lengths - items that are mutually exclusive, i.e. it either has to be one or the other. But options should be a bar chart or the like.
