Controlling the Axes
axis command supports a number of options for setting the scaling, orientation, and aspect ratio of plots. You can also set these options interactively. See Editing Plots for more information.
Setting Axis Limits
By default, MATLAB finds the maxima and minima of the data to choose the axis limits to span this range. The
axis command enables you to specify your own limits
or for three-dimensional graphs,
