There are a variety of circumstances where we might want to show two or even three intervals of uncertainty around each measured data point. The most frequent involves a wider interval between SCLs for comparing values with a numerical scale and a narrower interval between SPLs for comparing results with one another. In that circumstance, the use of double open triangular arrowheads a DOTAR display is particularly useful. Having chosen a graphical style, we need quantitative insight and numerical tables to implement our choice. In particular, we need to recognize the distinction between severe simultaneous and tight simultaneous and the possibility of finding, and using, severe simultaneous SCLs and SPLs at large exception rates. Numerical tables that outline quantitative behavior are provided.
