When evaluating this:

Table[n -> NumberLinePlot[{Range[n], Range[n]+.1}], {n, 4}]

we get this output:

enter image description here

Why is it different for n=2? Looks like a bug to me. Is there a workaround ?

This was evaluated with Mathematica 10.1 under Windows 7.

    $\begingroup$ I think the $n=2$ case is unique in that the pairs of values are interpreted as the two intervals $[1, 2]$ and $[1.1, 2.1]$. Compare with NumberLinePlot[{ {{1, 2}}, {{1.1, 2.1}} }]. $\endgroup$

As @MarcoB says in the comments this is because the $n=2$ case is being interpreted as a set of two intervals rather than two separate intervals (where "interval" can also mean "points").

Functions like ListLinePlot have an option setting like DataRange -> All | Automatic to distinguish between cases like this but NumberLinePlot does not seem to have anything similar.

However as per the first example in the Scope > Data section of the documentation the solution is to wrap List around the first number line:

Table[NumberLinePlot[{{Range[n]}, Range[n] + 0.1}], {n, 4}]
