I am trying to maintain the position of an 'edit box' in a resizeable GUI by the origin of a Cartesian plot. The position of the axes object is of course known.
How do I determine the location of the origin of the plot relative the position of the object? is there another way to find the position of the origin of the plot?
Thanks for any assistance

i would try looking at the 'position' property of the axes against the limits; the following works for figures, and seems to for axes in GUIs from a quick check...
hh = gca;
xRange = hh.XLim(2) - hh.XLim(1);
xFract = (0 - hh.XLim(1))/xRange;
xO = hh.Position(1) + xFract*hh.Position(3);
yRange = hh.YLim(2) - hh.YLim(1);
yFract = (0 - hh.YLim(1))/yRange;
yO = hh.Position(2) + yFract*hh.Position(4);
disp(['origin at (' num2str(xO) ',' num2str(yO) ')']);
