Plotting an axis on a scatter3 figure

Hello I would like to display an axis centered on [0,0,0] of a scatter 3 plot.

Is there a way to do this using the line function?

Not quite sure how to interpret it. Would greatly appreciate a hand.

If you just need the axes try adding:

hold on;
line(xlim,[0,0],[0,0]);
line([0,0],ylim,[0,0]);
line([0,0],[0,0],zlim);

After your scatter plot.

EDIT:

If you want to place the axes with origin at another point, you can do as follows:

hold on;
line(xlim,[origin(2),origin(2)],[origin(3),origin(3)]);
line([origin(1),origin(1)],ylim,[origin(3),origin(3)]);
line([origin(1),origin(1)],[origin(2),origin(2)],zlim);

Where origin is the point where you want the axes to meet.
