I am trying to adapt a common means of depicting blood biomarker data, where your value is shown as being either within or out of a reference range. Now I could just present a table with the value and the reference range, but I'm trying to plot out something more like this example. There is a completely different way that I tried using parallel plots to basically show if a biomarker was within spec limits, but I honestly feel like this plot is ugly and hard to read (second attachment). I would only want to depict results from a single sample at a time or it would be too complex (and so will use a local data filter), but I am wondering if there are control charts that are effectively doing exactly what I want: depicting where your value falls along a pre-set reference interval. I feel fairly confident I can do better than this parallel plot (!), so any suggestions would be appreciated.
