rectangle
Create rectangle with sharp or curved corners
Syntax
Description
rectangle('Position', creates
a rectangle in 2-D coordinates. Specify pos)pos as
a four-element vector of the form [x
y w h] in data units. The x and y elements
determine the location and the w and h elements
determine the size. The function plots into the current axes without
clearing existing content from the axes.
rectangle('Position', adds
curvature to the sides of the rectangle. For different curvatures
along the horizontal and vertical sides, specify pos,'Curvature',cur)cur as
a two-element vector of the form [horizontal vertical].
For the same length of curvature along all sides, specify cur as
a scalar value. Specify values between 0 (no curvature) and 1 (maximum
curvature). Use [1 1] to create an ellipse or circle.
rectangle(___, specifies
rectangle properties using one or more name-value pair arguments.
For example, Name,Value)'FaceColor','red' specifies a red
fill color. You can specify rectangle properties with any of the input
argument combinations in the previous syntaxes.
rectangle( creates
the rectangle in the axes specified by ax,___)ax instead
of in the current axes (gca). The option ax can
precede any of the input argument combinations in the previous syntaxes.
r = rectangle(___)r to modify properties
of the rectangle after it is created. For a list of properties, see Rectangle Properties. You can return
an output argument with any of the previous syntaxes.
Examples
Draw Rectangle
Draw a rectangle that has a lower left corner at the point (1,2). Make the width of the rectangle 5 units and the height 6 units. Then, change the axis limits.
rectangle('Position',[1 2 5 6])
axis([0 10 0 10])
Draw Rectangle with Curved Edges
Draw a rectangle that has a lower left corner at (0,0) and an upper right corner at (2,4). Create the rectangle with curved corners by specifying the curvature as the scalar value 0.2. For data units of equal length along both the x-axis and y-axis, use axis equal.
figure rectangle('Position',[0 0 2 4],'Curvature',0.2) axis equal
Add a second rectangle that has the shortest side completely curved by specifying the curvature as the scalar value 1.
rectangle('Position',[3 0 2 4],'Curvature',1)
Add a third rectangle and use different curvatures along the horizontal and vertical sides. Use a horizontal curvature of 0.5 to make 50 percent of each horizontal side curved. Use a vertical curvature of 1 to make both vertical sides completely curved.
rectangle('Position',[6 0 2 4],'Curvature',[0.5,1])
Draw Circle
Draw a circle by setting the Curvature property to [1 1]. Draw the circle so that it fills the rectangular area between the points (2,4) and (4,6). The Position property defines the smallest rectangle that contains the circle.
pos = [2 4 2 2]; rectangle('Position',pos,'Curvature',[1 1]) axis equal
Draw a red rectangle using the same position values to show how the circle fills the rectangular area.
rectangle('Position',pos,'EdgeColor','r')
Specify Rectangle Outline and Fill Color
Draw a rectangle and specify the fill color, outline color, and outline width.
rectangle('Position',[1,2,5,10],'FaceColor',[0 .5 .5],'EdgeColor','b',... 'LineWidth',3)
Modify Rectangle After Creation
Add a rectangle to the current axes and return the rectangle object, r.
r = rectangle('Position',[0 0 1 1]')
r =
Rectangle with properties:
FaceColor: 'none'
EdgeColor: [0 0 0]
LineWidth: 0.5000
LineStyle: '-'
Curvature: [0 0]
Position: [0 0 1 1]
Show all properties
Modify the rectangle after creation using r. Change the fill color, outline color, and outline width.
r.FaceColor = [0 .5 .5];
r.EdgeColor = 'b';
r.LineWidth = 3;
Input Arguments
pos — Size and location of rectangle
four-element vector of the form [x y w h]
Size and location of the rectangle, specified as a four-element
vector of the form [x y w h]. The x and y elements
define the coordinate for the lower left corner of the rectangle.
The w and h elements define
the dimensions of the rectangle.
All values are in data units.
Example: rectangle('Position',[0.5 0.5 0.3 0.4])
Data Types: double | single | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64
cur — Amount of horizontal and vertical curvature
[0 0] (default) | two-element vector | scalar
Amount of horizontal and vertical curvature, specified as a two-element vector or a scalar value. Use this property to vary the shape of the rectangle from rectangular to ellipsoidal.
The horizontal curvature is the fraction of the width that is curved along the top and bottom edges. The vertical curvature is the fraction of the height that is curved along the left and right edges.
To use different horizontal and vertical curvatures, specify a two-element vector of the form
[horizontal vertical]. Thehorizontalelement determines the horizontal curvature and theverticalelement determines the vertical curvature. Specify the values between 0 (no curvature) and 1 (maximum curvature). For example, a value of[0 0]creates a rectangle with square edges and value of[1 1]creates an ellipse.To use the same curvature for the horizontal and vertical edges, specify a scalar value between 0 and 1, inclusive. The shorter dimension determines the length of the curvature.
Example: [0.5 0.6]
Example: 0.75
Data Types: double
ax — Axes object
axes object
Axes object. If you do not specify an axes object, then rectangle uses
the current axes.
Name-Value Pair Arguments
Specify optional
comma-separated pairs of Name,Value arguments. Name is
the argument name and Value is the corresponding value.
Name must appear inside quotes. You can specify several name and value
pair arguments in any order as
Name1,Value1,...,NameN,ValueN.
rectangle('Position',[0 0 1 1],'EdgeColor','k','FaceColor',[0
.5 .5])Fill color, specified as an RGB triplet, a hexadecimal color code, a color name, or a short name.
For a custom color, specify an RGB triplet or a hexadecimal color code.
An RGB triplet is a three-element row vector whose elements specify the intensities of the red, green, and blue components of the color. The intensities must be in the range
[0,1]; for example,[0.4 0.6 0.7].A hexadecimal color code is a character vector or a string scalar that starts with a hash symbol (
#) followed by three or six hexadecimal digits, which can range from0toF. The values are not case sensitive. Thus, the color codes'#FF8800','#ff8800','#F80', and'#f80'are equivalent.
Alternatively, you can specify some common colors by name. This table lists the named color options, the equivalent RGB triplets, and hexadecimal color codes.
