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 rectangle object.
ColorSpec {[0 0 0]} | none |
Color of the object's edges. A three-element RGB vector or one of the MATLAB predefined names, specifying the edge color.
See the ColorSpec reference page for more information on specifying color.
Scalar alpha value in range [0 1]
Transparency of object background. This property defines the degree to which the object's background color is transparent. A value of 1 (the default) makes to color opaque, a value of 0 makes the background completely transparent (i.e., invisible). The default FaceAlpha is 1.
{flat} | none | ColorSpec
Color of filled areas. This property can be any of the following:
ColorSpec — A three-element RGB vector or one of the MATLAB predefined names, specifying a single color for all filled areas. See ColorSpec for more information on specifying color.
none — Do not draw faces. Note that EdgeColor is drawn independently of FaceColor
flat — The color of the filled areas is determined by the figure colormap. See colormap for information on setting the colormap.
See the ColorSpec reference page for more information on specifying color.
{-} | -- | : | -. | 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).
