yticks

Set or query y-axis tick values

Syntax

yticks(ticks)

yt = yticks

yticks('auto')

yticks('manual')

m = yticks('mode')

___ = yticks(ax,___)

Description

yticks(ticks) sets the y-axis tick values, which are the locations along the y-axis where the tick marks appear. Specify ticks as a vector of increasing values; for example, [0 2 4 6]. This command affects the current axes.

yt = yticks returns the current y-axis tick values as a vector.

yticks('auto') sets an automatic mode, enabling the axes to determine the y-axis tick values. Use this option if you change the tick values and then want to set them back to the default values.

yticks('manual') sets a manual mode, freezing the y-axis tick values at the current values. Use this option if you want to retain the current tick values when resizing the axes or adding new data to the axes.

m = yticks('mode') returns the current y-axis tick values mode, which is either 'auto' or 'manual'. By default, the mode is automatic unless you specify tick values or change the mode to manual.

___ = yticks(ax,___) uses the axes specified by ax instead of the current axes. Specify ax as the first input argument for any of the previous syntaxes.

Examples

Specify y-Axis Tick Values and Labels

Create a line plot. Display tick marks along the y-axis at the values 0, 50, and 100. Then, specify a label for each tick mark.

x = linspace(0,10);
y = x.^2;
plot(x,y)
yticks([0 50 100])
yticklabels({'y = 0','y = 50','y = 100'})

Specify Nonuniform y-Axis Tick Values

Display tick marks along the y-axis at nonuniform values between 0 and 25. MATLAB® labels the tick marks with the numeric values.

x = linspace(-5,5);
y = x.^2;
plot(x,y)
yticks([0 2 4 6 8 10 15 25])

Increment y-Axis Tick Values by 25

Display tick marks along the y-axis at increments of 25, starting from 0 and ending at 100.

x = linspace(0,10);
y = x.^2;
plot(x,y)
yticks(0:25:100)

Set y-Axis Tick Values Back to Default Values

Create a stem chart and specify the y-axis tick values. Then, set the y-axis tick values back to the default values.

stem(1:10)
yticks([0 5 10])

yticks('auto')

Specify y-Axis Tick Values for Specific Axes

Starting in R2019b, you can display a tiling of plots using the tiledlayout and nexttile functions. Call the tiledlayout function to create a 2-by-1 tiled chart layout. Call the nexttile function to create the axes objects ax1 and ax2. Plot data into each axes. Set the y-axis ticks for the lower plot by passing ax2 as the first input argument to the yticks function.

tiledlayout(2,1)
ax1 = nexttile;
plot(rand(3))

ax2 = nexttile;
plot(rand(3))
yticks(ax2,0:.2:1)

Remove y-Axis Tick Marks

Remove the tick marks along the y-axis by specifying the tick values as an empty array.

x = linspace(0,10);
y = sin(x);
plot(x,y)
yticks([])

Input Arguments

ticks — Tick values

vector of increasing values

Tick values, specified as a vector of increasing values. If you do not want tick marks along the y-axis, specify an empty vector [].

You can specify the tick values as numeric, categorical, datetime, or duration values. However, the type of values that you specify must match the type of values along the y-axis.

Example: yticks([pi 2*pi 3*pi 4*pi])

Example: yticks(0:10:100)

Example: yticks([])

Note

To specify the tick labels, use the yticklabels function.

Data Types: single | double | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64 | categorical | datetime | duration

ax — Target axes

Axes object | array of Axes objects

Target axes, specified as an Axes object or an array of Axes objects.

If you do not specify this argument, then yticks modifies the current axes.

Output Arguments

yt — Current tick values

vector

Current tick values, returned as a vector.

m — Current mode

'auto' | 'manual'

Current mode, returned as one of these values:

• 'auto' — Automatically determine the y-axis tick values.

• 'manual' — Use manually specified y-axis tick values.

More About

Tick Values

The tick values are the locations along the y-axis where the tick marks appear. The tick labels are the labels that you see next to each tick mark. Set the tick values using the yticks function. Set the corresponding tick labels using the yticklabels function.

Algorithms

The yticks function sets and queries several axes properties related to the y-axis tick values.

• YTick — Property that stores the y-axis tick values.

• YTickMode — Property that stores the y-axis tick value mode. When you set the y-axis tick values, this property changes to 'manual'.
