Understanding Axes Aspect Ratio
Axes shape graphics objects by setting the scaling and limits of each axis. When you create a graph, MATLAB automatically determines axis scaling based on the values or size of the plotted data, and then draws the axes to fit the space available for display. Axes aspect ratio properties control how MATLAB performs the scaling required to create a graph.
This section discusses MATLAB default behavior as well as techniques for customizing graphs.
By default, the size of the axes MATLAB creates for plotting is normalized to the size of the figure window (but is slightly smaller to allow for borders). If you resize the figure, the size and possibly the aspect ratio (the ratio of width to height) of the axis changes proportionally. This enables the axes to always fill the available space in the window. MATLAB also sets the x-, y-, and z-axis limits to provide the greatest resolution in each direction, again optimizing the use of available space.
This stretch-to-fill behavior is generally desirable; however, you may want to control this process to produce specific results. For example, images need to be displayed in correct proportions regardless of the aspect ratio of the figure window, or you may want graphs always to be a particular size on a printed page.
