What is wrong with my inputs for 'scatter3'?

I need help using 'scatter3' to make a 3d dot plot.
My inputs are:
x = 20000 x 1 datetime
y= 1 x 9 double
z = 9 x 20000 double
I'm trying scatter3(x,y,z). I keep getting an error saying: 'X, Y, Z, and size arguments must be vectors of the same length, matrices of the same size, or a mix of vectors and matrices where the length of the vectors matches either the number of rows or columns of the matrices."
I don't understand why I'm getting problems? Both the x and y lengths matches the row/column lengths of Z.
It works when I use surf, but not scatter3.
Thanks in advance!

% x, y, z similar to yours:
x = datetime(1e4*rand(200,1)+7.2e5,'ConvertFrom','datenum');
y = rand(1,9);
z = rand(9,200);
% make matrices X and Y by repeating elements
% of x and y in a particular manner:
[X,Y] = meshgrid(x,y);
% use scatter3 with 3 matrices of the same size:
scatter3(X,Y,z)
