MATLAB: Finding the location of the axis end in normalized coordinates

axescordinatesMATLABplot

Hello,
I have a problem with determining the end of the axis in normalized coordinates.
I found the begining of the axes with the function:
ax=axes();
p=get(ax,'Position');
which leads to:
p =
0.1300 0.1100 0.7750 0.8150
Then:
limits=xlim()
limits =
0 1
So I thought that the x-axis is ending at the 1, but after using this function:
annotation('textarrow',[p(1),p(3)],[p(2),p(2)]);
I got this:
As you can see, arrow ends somewhere between 0.8 and 0.9.
I am trying to find the position of the x, y point on the plot in normalized coordinates as I need to automate the annotation insertion on automatically generated graphs.
With best regards

You just missed the fact that end of axis is starting point + width, try this
ax=axes();
p=get(ax,'Position');
annotation('textarrow',[p(1), p(1) + p(3)],[p(2), p(2)]);
