Category: Graphics > Formatting and Annotation

Syntax

xlabel(txt)

Sets the x-axis label of the current axes.

xlabel(txt, Name, Value)

Sets text properties such as 'FontSize' or 'Color'.

xlabel(target, ___)

Labels the axes or tiled layout target.

t = xlabel(___)

Returns the text object.

Description

The label is centered under the x-axis. It is stored in the axes as XLabel, so a second call replaces the first. TeX markup such as \alpha or t_{max} is interpreted by default.

With a tiled layout as target, the label is shared by the whole grid and appears once under it.

Input arguments

txt: Label as text, a string array or a cell array of lines (a multi-line label).

Output arguments

t: Text object, class matlab.graphics.primitive.Text.

Example

Label with units and TeX

t = 0:0.1:5;
plot(t, exp(-t))
h = xlabel('time t (s)');
ylabel('\alpha(t)')
h.String

Output

ans = 'time t (s)'
