Transform Axes units to Normalized Units for Annotation Objects

10 Aug 2005 (Updated 09 Jan 2006)

Transforms axes units to normalized units for annotation objects.

File Information
Description	The annotation() function in MATLAB requires the X and Y coordinates for the object in normalized units. However, to accurately place objects, (without using GUI) we would like to give the annotation function the coordinates in terms of the current axes. This function transforms the axes coordinates that you enter, into normalized units that can be conveniently used in the annotation function.
MATLAB release	MATLAB 7 (R14)

10 Feb 2006	David Mays	The arrows look good on the screen, but their location is slightly wrong when I send the image to my HP LaserJet 1320 printer, to a TIFF file, or to an EPS file. I am using Matlab 7.1 Student Version on Windows XP Professional. This is unfortunate, because this function is very good except for this defect. I would fix it myself, if I could program as well as the author.

12 Jan 2007	Mark Harrington	Noticed strange results when the figure window is docked in 2006b. The annotations are no longer aligned with the data points, using a semilogx axes.

Updates
15 Aug 2005	The function now works for both log an linear scales and also for reversed axes.
15 Aug 2005	This update removes the limitations of the previous version in regards to a log scale and a reversed scale. Now it is possible to pass this information as arguments to the transform. read the .m file for detailed description.
09 Jan 2006	now the function automatically checks for reverse/normal and log/linear status of the axes. all you need to do is enter the axes coordinates of where you want to place an annotation object.
