See axis and axes for more …Graphics. Setting Aspect Ratio. By default, MATLAB displays graphs in a rectangular axes that has the same aspect ratio as the figure window. This makes optimum use of space available for plotting. MATLAB provides control over the aspect ratio with the axis command. For example, t = 0:pi/20:2*pi; plot (sin (t),2*cos (t)) grid on.When the plot box aspect ratio mode is auto, MATLAB sets the ratio to [1 1 1] , but may change it to accommodate manual settings of the data aspect ratio, camera view angle, or axis limits. See the axes DataAspectRatio property for a table listing the interactions between various properties. Image segmentation is the process of partitioning an image into parts or regions. This division into parts is often based on the characteristics of the pixels in the image. For example, one way to find regions in an image is to look for abrupt discontinuities in pixel values, which typically indicate edges. These edges can define regions.Using the mouse, draw a rectangle over the portion of the image that you want to crop. Perform the crop operation by double-clicking in the crop rectangle or selecting Crop Image on the context menu. The cropped image appears in the figure window. The Crop Image tool returns the cropped area in the return variable, J.axis equal. Otherwise set the axes DataAspectRatio property. For example, Theme. Copy. set (gca,'DataAspectRatio', [10 1 1]) would mean that every 10 units of x is to have the same size as one unit of y -- which would make something of x width 10 and y height 1 into a square. 3 Comments.
