I was using ListPlot3D and noticed that it wasn't plotting the last elements of my two dimensional list. (i.e. My 5x10 matrix was only showing a 4x9 set of data). However, when I use just an arrayplot it works beautifully. A Simple set of data I used is below:

    Temp = Table[0, {10}, {5}];
    Temp[[1, 3]] = 10;
    Temp[[2, 2 ;; 4]] = 10;
    Temp[[3 ;; 8, All]] = 10;
    Temp[[9, 2 ;; 4]] = 10;
    Temp[[10, 3]] = 10;


Sample Array Plot

    ListPlot3D[Temp, InterpolationOrder -> 0, Mesh -> None]

When I use the 3D plot, only one point on the diamond show up and the far right side is missing. I specifically want InterpolationOrder = 0, because for my case I want it to be essentially a 3DArray plot.

    $\begingroup$ That's the correct behaviour. ListPlot3D draws a surface connecting points. InterpolationOrder -> 0 means it interpolates between points with a flat, horizontal surface. You have $5\times 10$ points, so you have $4\times 9$ intervals between the points, so you have also $4\times 9$ surfaces interpolating between the points. This thread might give you ideas on how to proceed to obtain the desired result. $\endgroup$

  • $\begingroup$ Ah, I see. I was under the impression it would plot each point and just give it a volume of sorts! I appreciate the explanation! $\endgroup$

For the requirement

I want it to be essentially a 3DArray plot.

you can use DiscretePlot3D using your Temp to define a function foo:

(foo[##2] = #) & @@@ (Join @@ MapIndexed[Flatten@{##} &, Temp, {2}]);

DiscretePlot3D[foo[t, u], {t, 1, 10}, {u, 1, 5}, ExtentSize -> Full, 
 BoxRatios -> {1, 1/2, 1}]
