NaN coordinates

[BeastyBlacksmith]

Currently rows or columns that contain NaNs are omitted, compare e.g.:

julia> @pgf a = Axis({unbounded_coords = "jump"}, Plot3({surf}, Coordinates([1,2,3], [1,2,3], [3 4 5; 3 4 5; 2 3 4]))
       ) |> print_tex
\begin{axis}[unbounded coords={jump}]
    \addplot3[surf]
        coordinates {
            (1,1,3)
            (2,1,3)
            (3,1,2)

            (1,2,4)
            (2,2,4)
            (3,2,3)

            (1,3,5)
            (2,3,5)
            (3,3,4)

        }
        ;
\end{axis}

julia> @pgf a = Axis({unbounded_coords = "jump"}, Plot3({surf}, Coordinates([1,2,3], [1,2,3], [NaN 4 5; 3 4 5; 2 3 4]))
       ) |> print_tex
\begin{axis}[unbounded coords={jump}]
    \addplot3[surf]
        coordinates {

            (2,1,3.0)
            (3,1,2.0)

            (1,2,4.0)
            (2,2,4.0)
            (3,2,3.0)

            (1,3,5.0)
            (2,3,5.0)
            (3,3,4.0)

        }
        ;
\end{axis}

julia> @pgf a = Axis({unbounded_coords = "jump"}, Plot3({surf}, Coordinates([NaN,2,3], [1,2,3], [2 4 5; 3 4 5; 2 3 4]))
       )

julia> print_tex(a)
\begin{axis}[unbounded coords={jump}]
    \addplot3[surf]
        coordinates {

            (2.0,1,3)
            (3.0,1,2)

            (2.0,2,4)
            (3.0,2,3)

            (2.0,3,5)
            (3.0,3,4)

        }
        ;
\end{axis}

I would have expected, that they show up as nan in the tex-file.

That's a specific feature of the Coordinates constructor (it is documented). The effect should be the same, non-finite coordinate tuples are ignored.

But you can get the nans if you insist with Table.

The effect should be the same

It's not quite the same since this errors

julia> @pgf a = Axis({unbounded_coords = "jump"}, Plot3({surf}, Coordinates([1,2,3], [1,2,3], [NaN 4 5; 3 4 5; 2 3 4]))
       )

And this doesn't

julia> @pgf a = Axis({unbounded_coords = "jump"}, Plot3({surf}, Table([1,2,3], [1,2,3], [NaN 4 5; 3 4 5; 2 3 4]))
       )

But I'll stick to Table then.
