xlabel, ylabel, zlabel (MATLAB Function Reference)

Label the x-, y-, and z-axis

xlabel('string')
xlabel(fname)
xlabel(...,'PropertyName',PropertyValue,...)
h = xlabel(...)

ylabel(...)
h = ylabel(...)

zlabel(...)
h = zlabel(...)

Description

Each Axes graphics object can have one label for the x-, y-, and z-axis. The label appears beneath its respective axis in a two-dimensional plot and to the side or beneath the axis in a three-dimensional plot.

xlabel('string')

labels the x-axis of the current Axes.

xlabel(fname)

evaluates the function fname, which must return a string, then displays the string beside the x-axis.

xlabel(...,'PropertName',PropertyValue,...)

specifies property name and property value pairs for the Text graphics object created by xlabel.

h = xlabel(...), h = ylabel(...), and h = zlabel(...)

return the handle to the Text object used as the label.

ylabel(...) and zlabel(...)

label the y-axis and z-axis, respectively, of the current Axes.

Remarks

Re-issuing an xlabel, ylabel, or zlabel command causes the new label to replace the old label.

For three-dimensional graphics, MATLAB puts the label in the front or side, so that it is never hidden by the plot.
