How to make a 3D plot of 41x41x41 datapoints

I have done some simulations creating 41x41x41 datapoint and I would like to plot this in 3D. The points are either 1 (good) or 0 (bad) (or 1 and NaN or anything like this) and I want to show the area of good points in a 3D plot but I have no idea to do this.

The figure can be a pointcloud or just a solid in the middle of the figure (all the good points should be close to each other)

EDIT: I've added a dummy file with some data (5x5x5) which I try to plot in 3D (ABC_test). I'll add some real data file when I have the data available.

You can have a look here to see different solutions to plot data in 3D:

You can also consider using the plot3 function:

These don't work for me. At least I can't get them to work :)

I've added a file to the openingpost (ABC_test) which I try to plot in 3D (I'll add some real data later when it's available)

I thought scatter plot ( https://mathworks.com/help/matlab/ref/scatter3.html ) would be the way to do it, but I can't get that to work either.

If you have the image processing toolbox, the easiest would be:

volshow(your3Dmatrix)

This can plot my data! Can I add axis and grid to this figure?

So it looks something like this scatter plot (but solid, or points can be okay too)
