A hybrid of part to whole and nominal comparison graphs

Posted on April 27th, 2012 by Chris Twigg

After an intensely busy period, it’s nice to be back and looking at developments in the field. I came across some work from an ex student of mine Ben Willers earlier.

For some time I’ve been thinking about visualising part to whole relationships whilst effectively allowing for a means to draw comparisons between those parts. My earlier work in progress had such a part to whole chart in which I was always mindful about the problem of only one of the category measures starting at zero, this despite other aesthetic decisions that needed to be taken in balance.

Ben’s work looks at this problem in an interesting way, in a kind of hybrid part to whole / nominal comparison chart setup (extract pic below). However I do think that this method has some pitfalls too, as I mention over on Ben’s blog.
