How to pin an object from command

I read the tutorial and want to pin an annotation object, but I am creating them from a function. Is there a way to pin them to a point as an option of the annotation function? The tutorials only specify how to do it by selecting it from the menus.

Thanks!

use annotation() and specify the position.

Follow this link. You need to create a function which is provided. http://www.mathworks.com/help/techdoc/creating_plots/bquk5ia-1.html

But then when the user zooms the arrow are relative to the figure and not the axis and get out of place. I want them to stay pointing towards a point on the axis regardless of the zoom level.

Thanks for answering though!
