chose the marker with plot3d

Hello, i want to plot a 3d point with - marker. when i use plot3d(x,y,z,'-black') , I don't see anything on the figure but with plot(x,y,z,'.black') i have the right figure. could anyone tell me why please?

It looks like you used a hyphen instead of an underscore.

x = 1:5;
y = rand(1,5);
z = rand(1,5);

figure
plot3(x,y,z,'black','Marker','_','MarkerSize',16)

it doesn't work. i have this error

Error using plot3

'_' is not a valid value. Use one of these values: '+' | 'o' | '*' | '.' | 'x' | 'square' | 'diamond' | 'v' | '^' | '>'

| '<' | 'pentagram' | 'hexagram' | 'none'.

Hm. You can see that the code works here [R2022a].

You mention that you are using R2019b, so I guess it could be a bug that was fixed.
