This should be native on MATLAB.
28 Nov 2009 Connecting Two Points connecting two points with a line with arrowhead Author: Kang Zhao Dabirmoghaddam, Ali

I was looking for a built-in method of drawing arrows in MATLAB for hours. I could not find any, but this is exactly what I was looking for. Thank you, Kang.
22 Aug 2008 Trace the Position of Cursor without Click It works like GINPUT provided by MATLAB,but traces the position of cursor without click ... Author: Kang Zhao P., Daniel

I haven't taken a look at the all code yet and I haven't done any testing yet, but there *might* be a bug: see lines 45 and 46. A variable named "left_origin" is defined in line 45, but it is never used.
In line 46, a variable named "left_origin_unitfig" is used. At this point, the variable still has the value it got in line 42. I don't know if that's intended or not.

Regards,
Daniel P.

Brilliant m file, Zhao. Thank you very much for sharing this with us. I noticed that your function returns only x coordinates on the axes twice rather than x and y coordinates at the same time. I invoke the function like this.
"f = figure;
a = axes;
h = plot(t,x);
set(f,'windowbuttonmotionfcn','gpos(a)'); "

Should there be anything wrong with this, please kindly let me know. But as far as I have tried, no errors at all.

To Frank, please note the argument when you invoke
"gpos(h)
set(h,'WindowButtonMotionFcn',@gpos)"

It requires string argument rather function handle. You need axes handle and figure handle as shown below.

f = figure;
a = axes;
plot(something you want)
set(f,'windowbuttonmotionfcn','gpos(a)');

Hope this helps. Please let me know if you have further problems.

HI ... can i have an example code to run your function ... I try with my example but doesn't work. Thanks

My Example is:

t = (0:0.05:1)';
d1 = sin(2*pi*t)*[1 2 3];
d2 = cos(2*pi*t)*[1 2 3];
h=plot(t,[d1 d2]);
gpos(h)
set(h,'WindowButtonMotionFcn',@gpos)
