Categories contain groups and groups contain options.

Category click totals are inclusive of group and option clicks. In other words, if you click on a group or option within a group, it adds a click to the category. In this regard, group total clicks are inclusive of option clicks.

Category bar width(as seen below) is based on total category clicks, which represents the actual total clicks. Group bar width is based on total group clicks. Option bar width is based on the highest number of clicks on an individual option independent of it's category or group.
