Gets or sets the number format of the x-axis tick labels.

Category: Graphics > Formatting and Annotation

Syntax

xtickformat(fmt)

Formats the tick labels with fmt, a sprintf-style specification such as '%.1f', or a name like 'usd'.

f = xtickformat

Returns the current format.

xtickformat(ax, ___)

Acts on the axes ax.

Description

The format controls how the numbers at the ticks are written, without changing where the ticks are. Adding a unit ('%d%%') or fixing the number of decimals avoids labels such as 0.30000000004.

If the labels were set by hand with xticklabels, the format has no visible effect until xticklabels('auto') is called.

Input arguments

fmt: Text such as '%d%%' or '%.2f', or 'usd', 'eur' for currency. For datetime axes it is a datetime format such as 'MMM dd'.

Output arguments

f: Current format as text.

Example

Percent labels

plot(0:10:100, (0:10).^2)
xtickformat('%d%%')
f = xtickformat
xticklabels

Output

f = '%d%%'
ans = 6×1 cell

    {'0%'  }
    {'20%' }
    {'40%' }
    {'60%' }
    {'80%' }
    {'100%'}
