It's a "100% stacked bar chart", see examples here. Only that in your case you have only one bar instead of many.

Here's a bit more on its characteristics that determine how the name is composed:

  • 100% because it includes all possible components and they add up to 100%
  • stacked, because they all show up on top of each other (as a single line) rather than side by side as conventional bar charts
  • it is also horizontal (left implicit above)
  • there's also an implicit reference line pointing at the middle
  • and clearly it falls into the wider category of bar charts
  • +1 really nice answer. I assume you do a bit of infographic/datavis design yourself? :)

  • @MichaelLai, kind of. I use a lot of exploratory data analysis in my research. More often than not I have to present publicly not only the results, but also how I arrived at them.
