You can set and query annotation object properties using the set and get functions and the Property Editor (displayed with the propertyeditor command).

Use the annotation function to create annotation objects and obtain their handles.

Annotation Arrow Property Descriptions

Properties You Can Modify

This section lists the properties you can modify on an annotation ellipse object.

Color of the arrow. A three-element RGB vector or one of the MATLAB predefined names, specifying the arrow color.

See the ColorSpec reference page for more information on specifying color.

Length of the arrow head. Specify this property in points (1 point = 1/72 inch). See also HeadWidth.

Style of the arrow head. Specify this property as one of the strings from the following table.

Head Style String	Head	Head Style String	Head
none		star4
plain		rectangle
ellipse		diamond
vback1		rose
vback2 (Default)		hypocycloid
vback3		astroid
cback1		deltoid
cback2
cback3

Width of the arrow head. Specify this property in points (1 point = 1/72 inch). See also HeadLength.

Line style. This property specifies the line style of the arrow stem. Available line styles are shown in the following table.

Specifier String	Line Style
-	Solid line (default)
--	Dashed line
:	Dotted line
-.	Dash-dot line
none	No line

The width of the arrow stem. Specify this value in points (1 point = ¹/₇₂ inch). The default LineWidth is 0.5 points.

X-coordinates of the beginning and ending points for arrow. Specify this property as a vector of x-axis (horizontal) values that specify the beginning and ending points of the arrow, units normalized to the figure.

Y-coordinates of the beginning and ending points for arrow. Specify this property as a vector of y-axis (vertical) values that specify the beginning and ending points of the arrow, units normalized to the figure.
