Which units should I use when working with Handle Graphics?

I would like to know when I should use normalized units and when should I use fixed units such as pixels or inches.

The units you use depend on what you are trying to do. If you are building a graphical user interface (GUI), then you should try using normalized units because it is easier to control the location and size of the uicontrols relative to each other and the figure.

Also, normalized units allow the object to expand and contract relative to the size of its parent.

If you would like the object to stay at some fixed location relative to its parent, then you should use inches, pixels, points, or centimeters. Since these are fixed measurements, altering the size of the window or printout will not effect the location of the object relative to its parent.
