I'm trying to plot a skeleton model using the coordinates of the joints.
I extracted the x,y, and z coordinates and saved them in 3 matrices.
I'm trying to plot the first row of each column then have a small pause and plot the next row of each matrix.
each row of the matrices correspond to the x,y, and z coordinates of the joints and together they make a frame.

Which part of it is causing a problem.
doc plot3
should help with this.
Though you should use the syntax that returns the handle the first time you plot and then only update the 'XData' and 'YData' on future updates to concatenate the new points, otherwise it will be slow updating.

data = randn(10, 3)
hold on
for ii = 1: length(data)
scatter3(data(ii,1),data(ii,2),data(ii,3))
pause(1)
end
