Specify Axis Limits
You can control where data appears in the axes by setting the x-axis, y-axis, and z-axis limits. You also can change where the x-axis and y-axis lines appear (2-D plots only) or reverse the direction of increasing values along each axis.
Change Axis Limits
Create a line plot. Specify the axis limits using the
ylim functions. For 3-D plots, use the
zlim function. Pass the functions a two-element vector of the form
x = linspace(-10,10,200); y = sin(4*x)./exp(x); plot(x,y) xlim([0 10]) ylim([-0.4 0.8])
Use Semiautomatic Axis Limits
Set the maximum x-axis limit to 0 and the minimum y-axis limit to -1. Let MATLAB choose the other limits. For an automatically calculated minimum or maximum limit, use
[X,Y,Z] = peaks; surf(X,Y,Z) xlabel('x-axis') ylabel('y-axis') xlim([-inf 0]) ylim([-1 inf])
Revert Back to Default Limits
Create a mesh plot and change the axis limits. Then revert back to the default limits.
[X,Y,Z] = peaks; mesh(X,Y,Z) xlim([-2 2]) ylim([-2 2]) zlim([-5 5])
xlim auto ylim auto zlim auto
Reverse Axis Direction
Control the direction of increasing values along the x-axis and y-axis by setting the
YDir properties of the
Axes object. Set these properties to either
'normal' (the default). Use the
gca command to access the
stem(1:10) ax = gca; ax.XDir = 'reverse'; ax.YDir = 'reverse';
Display Axis Lines through Origin
By default, the x-axis and y-axis appear along the outer bounds of the axes. Change the location of the axis lines so that they cross at the origin point
(0,0) by setting the
YAxisLocation properties of the
Axes object. Set
XAxisLocation to either
YAxisLocation to either
'origin'. These properties only apply to axes in a 2-D view.
x = linspace(-5,5); y = sin(x); plot(x,y) ax = gca; ax.XAxisLocation = 'origin'; ax.YAxisLocation = 'origin';
Remove the axes box outline.
