Controlling the Axes

The axis command provides a number of options for setting the scaling,

orientation, and aspect ratio of graphs. You can also set these options

interactively. See “Editing Plots” on page 3-17 for more information.

Setting Axis Limits

By default, MATLAB finds the m axima and minima of the data and chooses

theaxislimitstospanthisrange. The

axis command enables you to specify

your own limits:

axis([xmin xmax ymin ymax])

or for three-dimensional graphs,

axis([xmin xmax ymin ymax zmin zmax])

Use the command

axis auto

to reenable MATLAB automatic limit selection.

Setting the Axis Aspect Ratio

The axis command also enables you to specify a number of predefined m odes.

For example,

axis square

makes the x-axis and y-axis the same length.

axis equal

makes the individual tick m ark increments on the x-axes and y-axe s the s ame

length. This means

plot(exp(i*[0:pi/10:2*pi]))
