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. For an example of its use, see Positioning Annotations in Data Space in the MATLAB Graphics documentation.
This section lists the properties you can modify on an annotation doublearrow object.
ColorSpec
Color of the object. A three-element RGB vector or one of the MATLAB predefined names, specifying the object's color.
See the ColorSpec reference page for more information on specifying color.
scalar value in points
Length of the first arrowhead. Specify this property in points (1 point = 1/72 inch). See also Head1Width.
The first arrowhead is located at the end defined by the point x(1), y(1). See also the X and Y properties.
scalar value in points
Length of the second arrowhead. Specify this property in points (1 point = 1/72 inch). See also Head1Width.
The first arrowhead is located at the end defined by the point x(end), y(end). See also the X and Y properties.
select string from list
Style of the first arrowhead. Specify this property as one of the strings from the following table
select string from list
Style of the second arrowhead. Specify this property as one of the strings from the following table.

scalar value in points
Width of the first arrowhead. Specify this property in points (1 point = 1/72 inch). See also Head1Length.
scalar value in points
Width of the second arrowhead. Specify this property in points (1 point = 1/72 inch). See also Head2Length.
{-} | -- | : | -. | none
Line style. This property specifies the line style of the object. Available line styles are shown in the following table.
Specifier String | Line Style |
|---|---|
Solid line (default) | |
Dashed line | |
Dotted line | |
Dash-dot line | |
No line |
scalar
The width of linear objects and edges of filled areas. Specify this value in points (1 point = 1/72 inch). The default LineWidth is 0.5 points.
four-element vector [x, y, width, height]
Size and location of the object. Specify the lower left corner of the object with the first two elements of the vector defining the point x, y in units normalized to the figure (when Units property is normalized). The third and fourth elements specify the object's dx and dy, respectively, in units normalized to the figure.
{normalized} | inches | centimeters | points | pixels
position units. MATLAB uses this property to determine the units used by the Position property. All positions are measured from the lower left corner of the figure window. Normalized units interpret Position as a fraction of the width and height of the parent axes. When you resize the axes, MATLAB modifies the size of the object accordingly. pixels, inches, centimeters, and points are absolute units (1 point = 1/72 inch).
vector [Xbegin Xend]
X-coordinates of the beginning and ending points for line. Specify this property as a vector of x-axis (horizontal) values that specify the beginning and ending points of the line, units normalized to the figure.
vector [Ybegin Yend]
Y-coordinates of the beginning and ending points for line. Specify this property as a vector of y-axis (vertical) values that specify the beginning and ending points of the line, units normalized to the figure.
