Bug introduced in 8.0.4 or earlier and persisting through 11.0.1 or later
I have noticed cases where Line
produces dots in a graphics object when I think it shouldn't. The first of these is:
Line[{{0., 0.}}]
The second is:
Line[{{0., 0.}, {0., 0.}}]
Longer lists of same point do not produce dots. To see this evaluate
repeatPts [pt_, n_] := Line[ConstantArray[pt, n]]
Graphics[{Thickness[.125], repeatPts[{0., 0.}, #], repeatPts[{1., 1.}, #]},
ImageSize -> 50, Frame -> True, FrameTicks -> None, PlotRangePadding -> .3] & /@ Range[5]
Is this version or platform depended? I got the results shown above on with V9.0.1 running on OS X. Should it be considered a bug or a weird feature?
Line[..., VertexColors -> {Red, Blue}]
the result is quite surprising. $\endgroup$Point[]
on the other hand is rendered as a zero length line with a round endcap. $\endgroup$
