Properties of the text box - graphics objects:

By using get will show properties of the text box, the illustration is as shown below:

>> get(thand)

  BackgroundColor = none

  Color = [0 0 0]

  EdgeColor = none

  EraseMode = normal

  Editing = off

  Extent = [1.95862 -0.0670554 0.901149

   0.110787]

  FontAngle = normal

  FontName = Helvetica

  FontSize = [10]

FontUnits = points

  FontWeight = normal

  HorizontalAlignment = left

  LineStyle = -

  LineWidth = [0.5]

  Margin = [2]

  Position = [2 0 0]

  Rotation = [0]

  String = Sin(\pi)\rightarrow

  Units = data

  Interpreter = tex

  VerticalAlignment = middle

   etc.

However the Position specified was (2,0), the Extent is the real extent of the text box, that cannot be seen asthe BackgroundColor and EdgeColor are not identified. These can be changed by using set. For illustration, the following produces the outcome as shown in figure:

>> set(thand,'BackgroundColor',[0.8 0.8 0.8],. . .

  'EdgeColor',[1 0 0])

Whenever the Units property has the value of data, that is the default as shown, the Extent of the text box is given by a vector [x y width height] where x and y are the coordinates of the bottom left-hand corner of the text box.
