How to plot orthogonal coordinate axes arrows

[Yannos M]

Hello,

Does anybody know if there is a function for plotting the orthogonal coordinate axes arrows (the origin-reference arrows) in a Matlab 3D figure?


thanks,
Yannos

Yannos,

For central axis lines through an origin, you can use my File Exchange submission, oaxes, available here: http://www.mathworks.com/matlabcentral/fileexchange/30018

If you just want a small indicator for orientation, try Tiny Axis, available here: http://www.mathworks.com/matlabcentral/fileexchange/32168 (I haven't tested this one, but it looks interesting).

John,

Thanks a lot! really helpful. The second link looks more interesting and it's closer to what I want but it's not very well documented and it doesn't make sense to me...
especially the h input argument in the function

tinyaxis(h,'r','g','b');

I don't really get what is it..

Anyway, thanks a lot!

Try this

plot3([0 100],[0 0],[0 0],'r',[0 0],[0 100],[0 0],'g',[0 0],[0 0],[0 100],'b','linewidth',2);

you can also do this,

x = line([0 100],[0,0],[0,0],'color','r');
y = line([0 0],[0,100],[0,0],'color','g');
z = line([0 0],[0,0],[0,100],'color','b']);

Edited: "error in z"

x = line([0 100],[0,0],[0,0],'color','r');
y = line([0 0],[0,100],[0,0],'color','g');
z = line([0 0],[0,0],[0,100],'color','b');

you may also add,

linewidth

Example:

x = line([0 100],[0,0],[0,0],'color','r','linewidth',2);
