ylim(limitmethod)

ylim(limitmode)

yl = ylim

limmethod = ylim("method")

limmode = ylim("mode")

___ = ylim(target,___)

Description

Specify Limits

example

ylim(limits) sets the y-axis limits for the current axes or chart. Specify limits as a two-element vector of the form [ymin ymax], where ymax is greater than ymin.

example

ylim(limitmethod) specifies the limit method MATLAB^® uses for automatic limit selection. Specify the limit method as "tickaligned", "tight", or "padded". MATLAB sets the YLimitMethod property of the axes to the value you specify. The limit method is not supported for standalone visualizations.

You can specify the limitmethod argument without parentheses. For example, ylim tight enables tight y-axis limits.

example

ylim(limitmode) specifies automatic or manual limit selection. The limitmode can have either of two values:

"auto" — Enable automatic limit selection. MATLAB selects the limits based on the range of your data and the value of the YLimitMethod property of the axes. If you plot into the axes multiple times, the limits update to encompass all the data.
"manual" — Freeze the y-axis limits at their current value.

You can specify the limitmode argument without parentheses. For example, ylim auto enables automatic limit selection.

Query Limits

example

yl = ylim returns the current limits as a two-element vector.

limmethod = ylim("method") returns the current y-axis limits method, which can be 'tickaligned', 'tight', or 'padded'.

limmode = ylim("mode") returns the current y-axis limits mode, which is either 'auto' or 'manual'. By default, the mode is automatic unless you specify limits or set the mode to manual.

Specify Target Axes or Chart

example

___ = ylim(target,___) uses the axes or standalone visualization specified by target instead of the current axes. Specify target as the first input argument for any of the previous syntaxes. You can include an output argument if the original syntax supports an output argument. Use quotes around the mode inputs, for example, ylim(target,"auto").

Set y-Axis Limits

Open Live Script

Plot a line and set the y-axis limits to range from -2 to 2.

x = linspace(0,10);y = sin(x);plot(x,y)ylim([-2 2])

Use Semiautomatic y-Axis Limits

Open Live Script

Create a surface plot and show only y values greater than 0. Specify the minimum y-axis limit as 0 and let MATLAB choose the maximum limit.

[X,Y,Z] = peaks;surf(X,Y,Z)ylim([0 inf])

Set Limits for y-Axis with Dates

Open Live Script

Create a horizontal bar chart with dates along the y-axis. Set the y-axis limits to range from June 1, 2014 to June 10, 2014.

t = datetime(2014,06,1) + caldays(0:20);y = rand(21,1);barh(t,y)tstart = datetime(2014,06,1);tend = datetime(2014,06,10);ylim([tstart tend])

Specify Tight y-Axis Limits

Open Live Script

Create a line plot.

x = 1:5; y = [-2.7 2 -1 4.2 0];plot(x,y)

Change the limit method to 'tight'.

ylim tight

Set y-Axis Limits for Specific Axes

Open Live Script

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. Then set the y-axis limits for the bottom plot by specifying ax2 as the first input argument to ylim.

tiledlayout(2,1)x = linspace(0,10,1000);y = sin(10*x).*exp(.5*x);ax1 = nexttile;plot(ax1,x,y)ax2 = nexttile;plot(ax2,x,y)ylim(ax2,[-10 10])

Maintain Current y-Axis Limits

Open Live Script

Use manual mode to maintain the current y-axis limits when you add more plots to the axes.

First, plot a line.

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

Set the y-axis limits mode to manual so that the limits to not change. Use hold on to add a second plot to the axes.

ylim manualhold ony2 = 2*sin(x);plot(x,y2)hold off

The y-axis limits do not update to incorporate the new plot.

Switch back to automatically updated limits by resetting the mode to automatic.

ylim auto

Return y-Axis Limits

Open Live Script

Create a scatter plot of random data. Return the values of the y-axis limits.

x = randn(50,1);y = randn(50,1);scatter(x,y)

yl = ylim

yl = 1×2 -2 3

`limits` — Minimum and maximum limits
two-element vector

Minimum and maximum limits, specified as a two-element vectorof the form [ymin ymax], where ymax isgreater than ymin. You can specify the limits asnumeric, categorical, datetime, or duration values. However, the typeof values that you specify must match the type of values along the y-axis.

You can specify both limits, or specify one limit and let MATLAB automatically calculate the other. For an automatically calculated minimum or maximum limit, use -inf or inf, respectively. MATLAB uses the 'tight' limit method to calculate the corresponding limit.

Example: ylim([0 1])

Example: ylim([-inf 1])

Example: ylim([0 inf])

`limitmethod` — Limit selection method
`"tickaligned"` (default) | `"padded"` | `"tight"`

Limit selection method, specified as a value from the table.

The examples in the table show the approximate appearance for each method. Your results might differ depending on your data, the size of the axes, and the type of plot you create.

Value	Description	Example
`"tickaligned"`	In general, align the edges of the axes box with the tick marks that are closest to your data without excluding any data. The appearance might vary depending on the type of data you plot and the type of chart you create.
`"tight"`	Fit the axes box tightly around the data by setting the axis limits to the data range.
`"padded"`	Fit the axes box around the data with a thin margin of padding on each side. The width of the margin is approximately 7% of the data range.

Note

The limit method has no effect when the YLimMode property of the axes is set to "manual".
Specifying the limit method is not supported for standalone visualizations such as heatmap.

`limitmode` — Limit mode
`"auto"` | `"manual"`

Limit mode, specified as one of the following values:

"auto" — Enable automatic limit selection, which is based on the total span of the data and the value of the YLimitMethod property of the axes. If you plot into the axes multiple times, the limits update to encompass all the data. You can use this option if you change the limits and want to set them back to the default values.
"manual" — Freeze the limits at the current values. Use this option if you want to retain the current limits when adding new data to the axes using the hold on command.

When you specify this argument, MATLAB sets the YLimMode property of the axes to the value you specify. However, the YLimMode property changes to "manual" whenever you set the y-axis limits explicitly, either by calling ylim(limits), or by setting the value of the YLim property on the axes.

`target` — Target axes or chart
axes object | standalone visualization | array of axes or standalone visualizations

Target axes or chart, specified as one of the following:

An Axes object.
A standalone visualization that has a YLimits property, such as a heatmap chart.
An array of axes or standalone visualizations that belong to the same class. To determine the class, use the class function.

If you do not specify this argument, then ylim sets the limits on the graphics object returned by the gca command.

Output Arguments

`yl` — Current limits
two-element vector

Current limits, returned as a two-element vector of the form [yminymax].

Querying the limits returns the YLim or YLimits property value for the corresponding Axes or graphics object.

`limmethod` — Current limits method
`'tickaligned'` | `'tight'` | `'padded'`

Current limits method, returned as one of these values:

'tickaligned' — In general, align the edges of the axes box with the tick marks that are closest to your data without excluding any data. The appearance might vary depending on the type of data you plot and the type of chart you create.
'tight' — Fit the axes box tightly around the data by setting the axis limits to the data range.
'padded' — Fit the axes box around the data with a thin margin of padding on each side. The width of the margin is approximately 7% of the data range.

Querying the y-axis limits method returns the YLimitMethod property value for the corresponding Axes object.

`limmode` — Current limits mode
`'auto'` | `'manual'`

Current limits mode, returned as one of these values:

'auto' — Automatically determine the limits.
'manual' — Use manually specified limits that do not update to reflect changes in the data.

Querying the y-axis limits mode returns the YLimMode property value for the corresponding Axes object.

Algorithms

The ylim function sets and queries severalaxes properties related to the y-axis limits.

YLim — Property that stores the y-axis limits.
YLimMode — Property that stores the y-axis limits mode. When you set the y-axis limits, this property changes to "manual".
YLimitMethod — Property that controls how the y-axis limits are calculated when the YLimMode property is set to "auto".
