Each strip is that field's whole ranked pool, with the notch where Physikalisch-Technische Bundesanstalt sits in it, in the colour of the band that rank falls in. The track under the rate is the rate itself: it carries no average mark, because the average differs by field (from about 6% in Dentistry to 21% in Economics).
