xticks — Query or set X-axis tick values.

xticks returns or updates the tick mark locations for the X axis of the current or specified axes.

Syntax

ticks = xticks()
ticks = xticks(ticks)
mode = xticks(mode)
ticks = xticks(ax, ticks)

How xticks works

• xticks() returns the current X-axis tick values as a row vector.
• xticks(ticks) sets manual X-axis tick values. ticks must be an increasing numeric vector; [] removes X-axis tick marks.
• xticks('auto') returns the X tick mode to automatic tick generation. xticks('manual') freezes the current tick values.
• xticks('mode') returns 'auto' or 'manual'.
• xticks(ax, ...) applies the same forms to the specified axes handle.
• get(ax, 'XTick'), set(ax, 'XTick', ticks), get(ax, 'XTickMode'), and set(ax, 'XTickMode', mode) share the same axes metadata.

GPU memory and residency

xticks only reads and writes axes metadata. It does not gather GPU-resident plot data; automatic ticks are generated from the axes display bounds, including explicit limits and cached plotted-data bounds.

Examples

Set nonuniform X-axis ticks

plot(-5:5, (-5:5).^2);
xticks([-5 -2.5 0 1 2.5 5]);

Expected output:

% Shows tick marks at the requested X coordinates

Reset X-axis ticks to automatic mode

xticks([0 5 10]);
xticks('auto');

Expected output:

% Restores automatic X tick generation

Using xticks with coding agents

Open a RunMat example with live inputs, then ask the agent to explain how xticks changes the result.
