The implication of this is that this method is pretty complex and less robust than the one I detail below, as it requires long formulas which hard code the number of dimensions. The alternative is simpler and more robust, and requires only 4 short calculations which don’t have to be tailored to the number of dimensions you intend to visualise, meaning you don’t require an understanding of trigonometry and you are able to filter dimensions from the view and your chart will automatically update. Thus, the formula you use will differ between a 5, 8 or 10 axis chart. In addition, within these calculations, the values need to be calculated within accordance worth how many “legs” you want your chart to have. I really like this view, apart from the range of average scores given when all sports are in the view – which I’ll need to work out how to fix.Īfter scouring YouTube videos and some blogs, I could only find very long and confusing calculations, in which something like this would be required for the X axis alone: I was anticipating this being pretty difficult, however, this took me very little time to create once I stumbled upon some good solutions. Nonetheless, I’ve seen a few on Twitter lately, and they reminded me of an old Makeover Monday in which ESPN rated 60 sports across 10 different categories, and I thought this would be a really good use case. However, they can also make comparison a little difficult this blog by Graham Odds details why radar charts aren’t always the best choice. Radar (or spider) charts can be an effective way to show certain types of data.
