Control axis with categorical values
CategoricalRuler
properties control the
appearance and behavior of an x-axis, y-axis, or
z-axis that shows categorical values. Each individual axis has its own
ruler object. By changing property values of the ruler, you can modify certain aspects of a
specific axis.
Use dot notation to refer to a particular ruler and property. Access the ruler objects
through the XAxis
, YAxis
, and ZAxis
properties of the Axes
object. For example:
ax = gca; co = ax.XAxis.Color; ax.XAxis.Color = 'blue';
Color
— Color of axis line and labels'r'
| 'g'
| 'b'
| ...Color of the axis line and labels, specified as an RGB triplet, a hexadecimal color code, a color name, or a short name.
For a custom color, specify an RGB triplet or a hexadecimal color code.
An RGB triplet is a three-element row vector whose elements
specify the intensities of the red, green, and blue
components of the color. The intensities must be in the
range [0,1]
; for example, [0.4
0.6 0.7]
.
A hexadecimal color code is a character vector or a string
scalar that starts with a hash symbol (#
)
followed by three or six hexadecimal digits, which can range
from 0
to F
. The
values are not case sensitive. Thus, the color codes
'#FF8800'
,
'#ff8800'
,
'#F80'
, and
'#f80'
are equivalent.
Alternatively, you can specify some common colors by name. This table lists the named color options, the equivalent RGB triplets, and hexadecimal color codes.
Color Name | Short Name | RGB Triplet | Hexadecimal Color Code | Appearance |
---|---|---|---|---|
'red' | 'r' | [1 0 0] | '#FF0000' | |
'green' | 'g' | [0 1 0] | '#00FF00' | |
'blue' | 'b' | [0 0 1] | '#0000FF' | |
'cyan'
| 'c' | [0 1 1] | '#00FFFF' | |
'magenta' | 'm' | [1 0 1] | '#FF00FF' | |
'yellow' | 'y' | [1 1 0] | '#FFFF00' | |
'black' | 'k' | [0 0 0] | '#000000' | |
'white' | 'w' | [1 1 1] | '#FFFFFF' | |
'none' | Not applicable | Not applicable | Not applicable | No color |
Here are the RGB triplets and hexadecimal color codes for the default colors MATLAB® uses in many types of plots.
RGB Triplet | Hexadecimal Color Code | Appearance |
---|---|---|
[0 0.4470 0.7410] | '#0072BD' | |
[0.8500 0.3250 0.0980] | '#D95319' | |
[0.9290 0.6940 0.1250] | '#EDB120' | |
[0.4940 0.1840 0.5560] | '#7E2F8E' | |
[0.4660 0.6740 0.1880] | '#77AC30' | |
[0.3010 0.7450 0.9330] | '#4DBEEE' | |
[0.6350 0.0780 0.1840] | '#A2142F' |
Note
The Color
property for the ruler and the associated
XColor
, YColor
, or
ZColor
property for the parent axes always have the same
value. Setting one also sets the other.
LineWidth
— Width of axis line and tick marks0.5
(default) | positive valueWidth of axis line and tick marks, specified as a positive value in point units. One point equals 1/72 inch.
Example: ax.XAxis.LineWidth = 2;
Note
Setting the LineWidth
property for the parent
axes sets the LineWidth
property for the ruler
to the same value. However, setting the ruler property does not set
the axes property. To prevent the axes property value from overriding
the ruler property value, set the axes value first, and then set the
ruler value.
Label
— Axis labelAxis label, which is a text object. To display text or change
existing text, set the String
property for the
text object. Use other properties to change the text appearance, such
as the font style or color.
ax = gca;
ax.XAxis.Label.String = 'X Axis';
ax.XAxis.Label.FontSize = 12;
For a full list of options, see Text Properties.
Alternatively, add or modify the axis labels using the xlabel
, ylabel
,
and zlabel
functions.
Note
The text object is not a child of the ruler object, so it cannot be
returned by findobj
and it does not use
the default text property values.
The text object stored in this property is the same as the text object
stored in the parent object’s label property. Thus, you can modify the text
object using either the ruler or the parent object’s property. For example,
setting the font size on a text object stored in an
x-axis ruler’s Label
property is the
same as setting the font size on the text object stored in the
XLabel
property of the parent axes.
LabelHorizontalAlignment
— Axis label horizontal alignment'center'
(default) | 'left'
| 'right'
Axis label horizontal alignment, specified as one of the values from the table.
LabelHorizontalAlignment Value | Description | Appearance |
---|---|---|
'center' | For a horizontal axis, the label is centered between the left and right edges of the plot box. For a vertical axis, the label is centered between the top and bottom edges of the plot box. |
|
'left' | For a horizontal axis, the label is aligned with the left edge of the plot box. For a vertical axis, the label is aligned with the bottom edge of the plot box. |
|
'right' | For a horizontal axis, the label is aligned with the right edge of the plot box. For a vertical axis, the label is aligned with the top edge of the plot box. |
|
Visible
— Axis visibility'on'
(default) | on/off logical valueAxis visibility, specified as 'on'
or 'off'
, or as
numeric or logical 1
(true
) or
0
(false
). A value of 'on'
is equivalent to true
, and 'off'
is equivalent to
false
. Thus, you can use the value of this property as a logical
value. The value is stored as an on/off logical value of type matlab.lang.OnOffSwitchState
.
'on'
— Display the axis.
'off'
— Hide the axis without deleting it. You
still can access properties of an invisible axis using the ruler
object.
Example: ax.XAxis.Visible = 'off';
Scale
— Scale of values along axis'linear'
(default)Scale of values along axis, specified as 'linear'
.
Direction
— Direction of increasing values'normal'
(default) | 'reverse'
Direction of increasing values, specified as one of these values:
'normal'
— Values increase
from left to right or bottom to top.
'reverse'
— Values increase
from right to left or top to bottom.
Note
The Direction
property for the ruler and
the associated XDir
, YDir
, or ZDir
property
for the parent axes always have the same value. Setting one also sets
the other.
Example: ax.XAxis.Direction = 'reverse';
Categories
— Categories plotted along axisCategories plotted along the axis, specified as a cell array of character vectors, a categorical array, or a string array. Querying this property returns a cell array of character vectors. Set this property to exclude certain categories from appearing in the chart.
Example: ax.XAxis.Categories =
categorical({'small','medium','large'})
specifies a categorical
array.
Example: ax.XAxis.Categories = {'small','medium','large'}
specifies a cell array.
Example: ax.XAxis.Categories = string({'small','medium','large'})
specifies a string array.
Create a histogram with categories along the x-axis and query the
Categories
property. Then set the Categories
property so that only a subset of categories appear along the
axis.
A = categorical({'r' 'b' 'g' 'g' 'r' 'b' 'b' 'r' 'g' 'y' 'g' 'm'}); h = histogram(A); ax = gca; ax.XAxis.Categories
ans = 1×5 categorical array b g m r y
ax.XAxis.Categories = categorical({'b','m','y'});
Data Types: cell
| categorical
| string
Limits
— First and last categories displayed along axisFirst and last categories displayed along the axis, specified as a two-element
vector indicating two category names. The categories must be two of the categories in
the Categories
property, and must appear in the same relative order
that they appear in the Categories
property.
Example: ax.XAxis.Categories = categorical({'small','medium'})
specifies a two-element categorical array.
Example: ax.XAxis.Categories = {'small','medium'}
specifies a
two-element cell array.
Example: ax.XAxis.Categories = string({'small','medium'})
specifies a two-element string array.
If you assign a value to this property, then MATLAB changes the associated LimitsMode
property to
'manual'
.
Alternatively, set the limits using the xlim
, ylim
, and zlim
functions.
Note
The Limits
property for the ruler and the associated
XLim
, YLim
, or ZLim
property for the parent axes always have the same value. Setting one also sets the
other.
Set the Limits
property to only show the categories between
'b'
and 'm'
along the axis.
A = categorical({'r' 'b' 'g' 'g' 'r' 'b' 'b' 'r' 'g' 'y' 'g' 'm'}); h = histogram(A); ax = gca; ax.XAxis.Limits = categorical({'b','m'});
Data Types: categorical
| string
| cell
LimitsMode
— Selection mode for Limits
property'auto'
(default) | 'manual'
Selection mode for the Limits
property, specified
as one of these values:
'auto'
— Automatically select
the axis limits based on the data plotted.
'manual'
— Use axis limit
values that you specify. To specify the axis limits, set the Limits
property.
Note
The LimitsMode
property for the ruler and
the associated XLimMode
, YLimMode
,
or ZLimMode
property for the parent axes always
have the same value. Setting one also sets the other.
TickValues
— Tick mark locations along the axisTick mark locations along the axis, specified as a cell array of character vectors,
a categorical array, or a string array indicating category names. The categories must be
a subset of the categories in the Categories
property and must
appear in the same relative order that they appear in the Categories
property. To remove all tick marks and labels along the axis, set this property to an
empty array []
.
Example: ax.XAxis.Categories =
categorical({'small','medium','large'})
specifies a categorical
array.
Example: ax.XAxis.Categories = {'small','medium','large'}
specifies a cell array.
Example: ax.XAxis.Categories = string({'small','medium','large'})
specifies a string array.
If you assign a value to this property, then MATLAB sets the TickValuesMode
property to
'manual'
.
Alternatively, use the xticks
, yticks
, and zticks
functions.
Note
The TickValues
property for the ruler and the associated
XTick
, YTick
, or ZTick
property for the parent axes always have the same value. Setting one also sets the
other.
Label a subset of categories along the axis by setting the
TickValues
property to a subset of
categories.
A = categorical({'r' 'b' 'g' 'g' 'r' 'b' 'b' 'r' 'g' 'y' 'g' 'm'}); h = histogram(A); ax = gca; ax.XAxis.TickValues = categorical({'b','m','y'});
Data Types: categorical
| string
| cell
TickValuesMode
— Selection mode for TickValues
property'auto'
(default) | 'manual'
Selection mode for the TickValues
property,
specified as one of these values:
'auto'
— Automatically select
the tick values based on the data plotted.
'manual'
— Use tick values
that you specify. To specify the values, set the TickValues
property.
Note
The TickValuesMode
property for the ruler
and the associated XTickMode
, YTickMode
,
or ZTickMode
property for the parent axes always
have the same value. Setting one also sets the other.
TickLabels
— Tick mark labels''
(default) | cell array of character vectors | string array | categorical arrayTick mark labels, specified as a cell array of character vectors, string array, or
categorical array. Use this property to relabel the tick marks without changing the
category names. If you do not specify a label for every value, then the labels repeat.
The labels support TeX and LaTeX markup. See the
TickLabelInterpreter
property for more information.
If you set this property, then MATLAB sets the TickLabelsMode
property to
'manual'
.
Alternatively, specify the tick labels using the xticklabels
, yticklabels
, and zticklabels
functions.
Note
If you specify this property as a categorical array, MATLAB uses the values in the array, not the categories.
The TickLabels
property for the ruler and the associated
XTickLabel
, YTickLabel
, or
ZTickLabel
property for the parent axes always have the same
value. Setting one also sets the other.
Relabel the categories along the x-axis.
A = categorical({'r' 'b' 'g' 'g' 'r' 'b' 'b' 'r' 'g' 'y' 'g'}); h = histogram(A); ax = gca; ax.XAxis.TickLabels = {'Blue','Green','Red','Yellow'}
Data Types: char
| string
| categorical
TickLabelsMode
— Selection mode for TickLabels
property'auto'
(default) | 'manual'
Selection mode for the TickLabels
property,
specified as one of these values:
'auto'
— Automatically select
the tick labels.
'manual'
— Use tick labels
that you specify. To specify the labels, set the TickLabels
property.
Note
The TickLabelsMode
property for the ruler
and the associated XTickLabelMode
, YTickLabelMode
,
or ZTickLabelMode
property for the parent axes
always have the same value. Setting one also sets the other.
TickLabelInterpreter
— Tick label interpreter'tex'
(default) | 'latex'
| 'none'
Tick label interpreter, specified as one of these values:
'tex'
— Interpret characters using a subset of TeX
markup.
'latex'
— Interpret characters using LaTeX markup.
When you specify the tick labels, use dollar signs around each element in the
cell array.
'none'
— Display literal characters.
Note
Setting the TickLabelInterpreter
property for the parent axes
sets the TickLabelInterpreter
property for the ruler to the same
value. However, setting the ruler property does not set the axes property. To
prevent the axes property value from overriding the ruler property value, set the
axes value first, and then set the ruler value.
By default, MATLAB supports a subset of TeX markup. Use TeX markup to add superscripts and subscripts, modify the text type and color, and include special characters in the text.
Modifiers remain in effect until the end of the text.
Superscripts and subscripts are an exception because they modify only the next character or the
characters within the curly braces. When you set the interpreter to 'tex'
,
the supported modifiers are as follows.
Modifier | Description | Example |
---|---|---|
^{ } | Superscript | 'text^{superscript}' |
_{ } | Subscript | 'text_{subscript}' |
\bf | Bold font | '\bf text' |
\it | Italic font | '\it text' |
\sl | Oblique font (usually the same as italic font) | '\sl text' |
\rm | Normal font | '\rm text' |
\fontname{ | Font name — Replace
with the name of
a font family. You can use this in combination with other modifiers. | '\fontname{Courier} text' |
\fontsize{ | Font size —Replace
with a numeric
scalar value in point units. | '\fontsize{15} text' |
\color{ | Font color — Replace
with one of
these colors: red , green ,
yellow , magenta ,
blue , black ,
white , gray ,
darkGreen , orange , or
lightBlue . | '\color{magenta} text' |
\color[rgb]{specifier} | Custom font color — Replace
with a
three-element RGB triplet. | '\color[rgb]{0,0.5,0.5} text' |
This table lists the supported special characters for the
'tex'
interpreter.

To use LaTeX markup, set the TickLabelInterpreter
property to
'latex'
. Use dollar symbols around the labels, for example,
use '$\int_1^{20} x^2 dx$'
for inline mode or
'$$\int_1^{20} x^2 dx$$'
for display mode.
The displayed text uses the default LaTeX font style. The
FontName
, FontWeight
, and
FontAngle
properties do not have an effect. To change the
font style, use LaTeX markup within the text. The maximum size of the text that you
can use with the LaTeX interpreter is 1200 characters. For multiline text, the
maximum size of the text reduces by about 10 characters per line.
For examples that use TeX and LaTeX, see Greek Letters and Special Characters in Chart Text. For more information about the LaTeX system, see The LaTeX Project website at https://www.latex-project.org/.
TickLabelRotation
— Rotation of tick labelsRotation of tick labels, specified as a scalar value in degrees. Positive values give counterclockwise rotation. Negative values give clockwise rotation.
Alternatively, you can rotate the tick labels using the xtickangle
, ytickangle
,
and ztickangle
functions.
Note
The TickLabelRotation
property for the ruler
and the associated XTickLabelRotation
, YTickLabelRotation
,
or ZTickLabelRotation
property for the parent axes
always have the same value. Setting one also sets the other.
Example: ax.XAxis.TickLabelRotation = 45;
Example: ax.YAxis.TickLabelRotation = -45;
TickLabelRotationMode
— Selection mode for TickLabelRotation
property'auto'
(default) | 'manual'
Selection mode for the TickLabelRotation
property,
specified as one of these values:
'auto'
— Automatically select
the tick label rotation.
'manual'
— Use a tick label
rotation that you specify. To specify the rotation, set the TickLabelRotation
property.
TickDirection
— Tick mark direction'in'
(default) | 'out'
| 'both'
Tick mark direction, specified as one of these values:
'in'
— Direct the tick marks
inward from the axis lines. This is the default for 2-D views.
'out'
— Direct the tick
marks outward from the axis lines. This is the default for 3-D views.
'both'
— Center the tick
marks over the axis lines.
If you assign a value to this property, then MATLAB sets
the TickDirectionMode
property to 'manual'
.
Note
Setting the TickDir
property for the parent
axes sets the TickDirection
property for the ruler
to the same value. However, setting the ruler property does not set
the axes property. To prevent the axes property value from overriding
the ruler property value, set the axes value first, and then set the
ruler value.
Example: ax.YAxis.TickDirection = 'out';
TickDirectionMode
— Selection mode for TickDirection
property'auto'
(default) | 'manual'
Selection mode for the TickDirection
property,
specified as one of these values:
'auto'
— Automatically select
the tick direction.
'manual'
— Use a tick direction
that you specify. To specify the tick direction, set the TickDirection
property.
TickLength
— Tick mark lengthTick mark length, specified as a two-element vector of the form [2Dlength
3Dlength]
. The first element is the tick mark length in
2-D views. The second element is the tick mark length in 3-D views.
Specify the values in units normalized relative to the longest axes
dimension.
Note
Setting the TickLength
property for the parent
axes sets the TickLength
property for the ruler
to the same value. However, setting the ruler property does not set
the axes property. To prevent the axes property value from overriding
the ruler property value, set the axes value first, and then set the
ruler value.
Example: ax.YAxis.TickLength = [0.02 0.035];
MinorTick
— Minor tick mark display'off'
(default) | on/off logical valueMinor tick mark display, specified as 'on'
or 'off'
, or
as numeric or logical 1
(true
) or
0
(false
). A value of 'on'
is equivalent to true
, and 'off'
is equivalent to
false
. Thus, you can use the value of this property as a logical
value. The value is stored as an on/off logical value of type matlab.lang.OnOffSwitchState
.
'on'
— Display minor tick marks between the
major tick marks on the axis. This is the default value for an axis with a
log scale. The space between the major tick marks determines the number of
minor tick marks. If the MinorTickValues
property is set
to empty []
, then no minor tick marks appear. Specify the
tick mark locations by setting the MinorTickValues
property.
'off'
— Do not display minor tick marks. This is
the default value for an axis with a linear scale.
Note
The MinorTick
property for the ruler and
the associated XMinorTick
, YMinorTick
,
or ZMinorTick
property for the parent axes always
have the same value. Setting one also sets the other.
Example: ax.XAxis.MinorTick = 'on';
MinorTickValues
— Minor tick mark locationsMinor tick mark locations, specified as a cell array of character vectors, a
categorical array, or a string array indicating category names. The categories must be a
subset of the categories in the Categories
property and must appear
in the same relative order that they appear in the Categories
property.
If you assign values to this property, then MATLAB sets the MinorTickValuesMode
property to
'manual'
.
Data Types: categorical
| string
| cell
MinorTickValuesMode
— Selection mode for MinorTickValues
property'auto'
(default) | 'manual'
Selection mode for the MinorTickValues
property,
specified as one of these values:
'auto'
— Use automatically
calculated minor tick values.
'manual'
— Use minor tick
values that you specify. To specify the values, set the MinorTickValues
property.
FontName
— Font name'FixedWidth'
Font name, specified as a system supported font name or 'FixedWidth'
.
The default font depends on the specific system and locale. To use
a fixed-width font that renders well, specify 'FixedWidth'
.
The actual fixed-width font used depends on the FixedWidthFontName
property
of the root object.
Note
Setting the FontName
property for the parent
axes sets the FontName
property for the ruler to
the same value. However, setting the ruler property does not set the
axes property. To prevent the axes property value from overriding
the ruler property value, set the axes value first, and then set the
ruler value.
Example: ax.XAxis.FontName = 'Cambria';
FontSize
— Font sizeFont size, specified as a scalar numeric value. The default font size depends on the specific operating system and locale.
Note
Setting the FontSize
property for the parent axes sets
the FontSize
property for the ruler to the same value.
However, setting the ruler property does not set the axes property. To
prevent the axes property value from overriding the ruler property value,
set the axes value first, and then set the ruler value.
Setting the FontSize
property on the ruler changes
the size of the tick labels. MATLAB also updates the font size of the corresponding axes label
using the LabelFontSizeMultiplier
of the parent axes.
For example, setting the font size of an x-axis ruler to
12
sets the font size for the
XLabel
property of the parent axes to
12
times the value of the
LabelFontSizeMultiplier
property.
Example: ax.XAxis.FontSize = 12;
FontWeight
— Thickness of text characters'normal'
(default) | 'bold'
Thickness of the text characters, specified as one of these values:
'normal'
— Default weight
as defined by the particular font.
'bold'
— Thicker character
outlines than normal.
MATLAB uses the FontWeight
property
to select a font from those available on your system. Not all fonts
have a bold font weight. Therefore, specifying a bold font weight
still can result in the normal font weight.
Note
Setting the FontWeight
property for the parent
axes sets the FontWeight
property for the ruler
to the same value. However, setting the ruler property does not set
the axes property. To prevent the axes property value from overriding
the ruler property value, set the axes value first, and then set the
ruler value.
Example: ax.XAxis.FontWeight = 'bold';
FontAngle
— Text character slant'normal'
(default) | 'italic'
Character slant, specified as 'normal'
or 'italic'
.
Not all fonts have both font styles. Therefore, the italic font can
look the same as the normal font.
Note
Setting the FontAngle
property for the parent
axes sets the FontAngle
property for the ruler
to the same value. However, setting the ruler property does not set
the axes property. To prevent the axes property value from overriding
the ruler property value, set the axes value first, and then set the
ruler value.
Example: ax.XAxis.FontAngle = 'italic';
FontSmoothing
— Text antialiasing'on'
(default) | on/off logical valueText smoothing, specified as 'on'
or 'off'
, or as
numeric or logical 1
(true
) or
0
(false
). A value of 'on'
is equivalent to true
, and 'off'
is equivalent to
false
. Thus, you can use the value of this property as a logical
value. The value is stored as an on/off logical value of type matlab.lang.OnOffSwitchState
.
'on'
— Enable text antialiasing to reduce the
jagged appearance of text characters and make the text easier to read. In
certain cases, smoothed text blends against the background color and can
make the text appear blurry.
'off'
— Disable text antialiasing. Use this
setting if the text seems blurry.
Note
Setting the FontSmoothing
property for the
parent axes sets the FontSmoothing
property for
the ruler to the same value. However, setting the ruler property does
not set the axes property. To prevent the axes property value from
overriding the ruler property value, set the axes value first, and
then set the ruler value.
Example: ax.XAxis.FontSmoothing = 'off';
LimitsChangedFcn
— Axis limits changed callback''
(default) | function handle | cell array | character vectorAxis limits changed callback, specified as one of these values:
A function handle.
A cell array in which the first element is a function handle. Subsequent elements in the cell array are the arguments to pass to the callback function.
A character vector containing a valid MATLAB expression (not recommended). MATLAB evaluates this expression in the base workspace.
This callback executes after the axis limits have changed, either programmatically or as a result of an interaction such as panning within the axes. It also executes if MATLAB changes the axis limits when you call a plotting function. Plotting functions can sometimes change the axis limits to encompass the range of your data.
This callback function can access specific information about the axis limits. MATLAB passes this information in a LimitsChangedData
object as the second argument to your callback function. If you are developing an app in App Designer, the argument is called event
. You can query the object properties using dot notation. For example, event.NewLimits
returns the new axis limits. The LimitsChangedData
object is not available to callback functions specified as character vectors.
The following table lists the properties of the LimitsChangedData
object.
Property | Description |
---|---|
Source | Ruler object that executes the callback |
EventName |
|
OldLimits | Two-element vector containing the previous axis limits |
NewLimits | Two-element vector containing the new axis limits |
For more information about writing callbacks in apps, see Write Callbacks in App Designer.
Parent
— Ruler parentAxes
objectRuler parent, specified as an Axes
object.
Note
Ruler objects are not listed in the Children
property
of the parent Axes
