3D Plot with line and dot

Hi guys,

I'm new matlab user, i would to know if is possible to plot a cube using line and dot.

I have already plotted a cube with scatter3(x,y,z) and I like it, but I need also to link each point with a line. The problem is that if I add a line with 'plot edit' but when I rotate the graph or zoom in/out the lines dosen't adjust with the graph.

How can I do?

Thanks for you time.

cornerX = [0 1 1 0 0 1 1 0];
cornerY = [0 0 1 1 0 0 1 1];
cornerZ = [0 0 0 0 1 1 1 1];

edges = [1 2;
         2 3;
         3 4;
         4 1;
         5 6;
         6 7;
         7 8;
         8 5;
         1 5;
         2 6;
         3 7
         4 8];

for i = 1:size(edges,1)
    line(cornerX(edges(i,:)), ...
         cornerY(edges(i,:)), ...
         cornerZ(edges(i,:)))
end

view(3)
xlim([-1 2]);
ylim([-1 2]);
zlim([-1 2]);

Very nice!

Would you know how to color the volume of the cube (not the edges) by some color?

(That color could represent a value from a color bar )

Look at the help file for the _patch_ function, assuming that it's acceptable to color the faces, rather than the entire volume.
