set(0,'DefaultAxes PropertyName',PropertyValue.).

You can set default axes properties on the figure and root levels: In this example, the first plot occupies the bottom two-thirds of the figure, and the second occupies the top third.Īxis, cla, clf, figure, gca, grid, subplot, title, xlabel, ylabel, zlabel, view You can define multiple axes in a single figure window: By default, MATLAB uses normalized units where (0,0) is the lower-left corner and (1.0,1.0) is the upper-right corner of the figure window. You specify these values in units determined by the Units property. The width and height elements define the dimensions of the rectangle. The left and bottom elements of this vector define the distance from the lower-left corner of the figure to the lower-left corner of the rectangle. Specify the location and size of the axes with a rectangle defined by a four-element vector,

h = axes('Position',position_rectangle)Ĭreates an axes object at the specified position within the current figure and returns a handle to it.

The axes Position property enables you to define the location of the axes within the figure window. Note that both examples disable the MATLAB stretch-to-fill behavior. Set(gca,'CameraViewAngle',get(gca,'CameraViewAngle')+5) Set(gca,'CameraViewAngle',get(gca,'CameraViewAngle')-5) Zoom in and out using the CameraViewAngle: In the picture above, the height of the rectangle constrains the axes size.

When stretch-to-fill is disabled, MATLAB sets the size of the axes to be as large as possible within the constraints imposed by the Position rectangle without introducing distortion. The dotted lines show the axes Position rectangle. This picture shows the same sphere displayed both with and without the stretch-to-fill.

However, stretch-to-fill is turned off when the DataAspectRatio, PlotBoxAspectRatio, or CameraViewAngle is user-specified, or when one or more of the corresponding modes is set to manual (which happens automatically when you set the corresponding property value). Stretch-to-fill is active when the DataAspectRatioMode, PlotBoxAspectRatioMode, and CameraViewAngleMode are all auto (the default). However, some 3-D graphs (such as a sphere) appear distorted because of this stretching, and are better viewed with a specific three-dimensional aspect ratio. This results in graphs that use the available space in the rectangle. While the basic purpose of an axes object is to provide a coordinate system for plotted data, axes properties provide considerable control over the way MATLAB displays data.īy default, MATLAB stretches the axes to fill the axes position rectangle (the rectangle defined by the last two elements in the Position property). The axis (not axes) function provides simplified access to commonly used properties that control the scaling and appearance of axes. Use the gca command to obtain the handle of the current axes. Use the set function to modify the properties of an existing axes or the get function to query the current values of axes properties. These properties, which control various aspects of the axes object, are described in the "Axes Properties" section.

The axes function accepts property name/property value pairs, structure arrays, and cell arrays as input arguments (see the set and get commands for examples of how to specify these data types). MATLAB automatically creates an axes, if one does not already exist, when you issue a command that draws image, light, line, patch, surface, or text graphics objects. Returns the handle of the created axes object.

The current axes is the target for functions that draw image, line, patch, surface, and text graphics objects. It also makes h the first axes listed in the figure's Children property and sets the figure's CurrentAxes property to h. MATLAB uses default values for any properties that you do not explicitly define as arguments.
