getting the axis position correctly

I can get the position of the axis easily
figure,plot([0 1], [0 1])
axis equal
AxesHandle=findobj(gcf,'Type','axes');
get(AxesHandle,'Position')
However when I modify the axis limits the axis position does not update.
axis tight
get(AxesHandle,'Position')
still gives me the same answer. How do I get the correct axis position in the second case?

What changes is the tightinset property and plotboxaspectratio.
figure,plot([0 1], [0 1])
axis equal
AxesHandle=findobj(gcf,'Type','axes');
pt1 = get(AxesHandle,{'Position','tightinset','PlotBoxAspectRatio'});
pt1{:}
axis tight
pt2 = get(AxesHandle,{'Position','tightinset','PlotBoxAspectRatio'});
pt2{:}

All you are doing here is moving the figure around. Of course this doesn't change the axes properties! Why would you think that moving the figure around would change the axes properties?
Also, you can use GCA to get the axes handle, just like GCF gets the figure handle...

If you want to get the distance between the edge of the figure and the axis plot area, you need to stop using normalized units and switch to pixels. Then you will see a change.....
figure,plot([0 1], [0 1])
set(gcf,'position', [104 468 1831 420])
axis equal
axis tight
set(gca,'units','pix')
pt1 = get(gca,{'Position','tightinset'}); % [left bottom right top]
set(gca,'units','norm')
pt1{:}
input('Hit return to continue...');
set(gcf,'position', [104 468 793 420])
set(gca,'units','pix')
pt2 = get(gca,{'Position','tightinset'});
set(gca,'units','norm')
pt2{:}

I wrote a little function that analyzes the aspect ratios and calculates the plotted axis region:
Should return exactly what you're looking for.

Thank you! This is exactly what I needed, in order to add annotations after making "axis equal."

The position remains the same, don't believe me? go to Tools and press Edit Plot, now click on the axis :)
One thing that do change is the:
