plot
2D line plot
Syntax
Description
Vector and Matrix Data
plot(
plots Y
)Y
against an implicit set of xcoordinates.
If
Y
is a vector, the xcoordinates range from 1 tolength(Y)
.If
Y
is a matrix, the plot contains one line for each column inY
. The xcoordinates range from 1 to the number of rows inY
.
If Y
contains complex numbers, MATLAB^{®} plots the imaginary part of Y
versus the real
part of Y
. If you specify both X
and
Y
, the imaginary part is ignored.
Table Data
plot(
plots the variables tbl
,xvar
,yvar
)xvar
and yvar
from the
table tbl
. To plot one data set, specify one variable for
xvar
and one variable for yvar
. To
plot multiple data sets, specify multiple variables for xvar
,
yvar
, or both. If both arguments specify multiple
variables, they must specify the same number of variables. (since
R2022a)
Additional Options
plot(
displays
the plot in the target axes. Specify the axes as the first argument in any of
the previous syntaxes.ax
,___)
plot(___,
specifies Name,Value
)Line
properties using one or more namevalue
arguments. The properties apply to all the plotted lines. Specify the namevalue
arguments after all the arguments in any of the previous syntaxes. For a list of
properties, see Line Properties.
p = plot(___)
returns a
Line
object or an array of Line
objects. Use p
to modify properties of the plot after
creating it. For a list of properties, see Line Properties.
Examples
Create Line Plot
Create x
as a vector of linearly spaced values between 0 and $$2\pi $$. Use an increment of $$\pi /100$$ between the values. Create y
as sine values of x
. Create a line plot of the data.
x = 0:pi/100:2*pi; y = sin(x); plot(x,y)
Plot Multiple Lines
Define x
as 100 linearly spaced values between $$2\pi $$ and $$2\pi $$. Define y1
and y2
as sine and cosine values of x
. Create a line plot of both sets of data.
x = linspace(2*pi,2*pi); y1 = sin(x); y2 = cos(x); figure plot(x,y1,x,y2)
Create Line Plot From Matrix
Define Y
as the 4by4 matrix returned by the magic
function.
Y = magic(4)
Y = 4×4
16 2 3 13
5 11 10 8
9 7 6 12
4 14 15 1
Create a 2D line plot of Y
. MATLAB® plots each matrix column as a separate line.
figure plot(Y)
Specify Line Style
Plot three sine curves with a small phase shift between each line. Use the default line style for the first line. Specify a dashed line style for the second line and a dotted line style for the third line.
x = 0:pi/100:2*pi; y1 = sin(x); y2 = sin(x0.25); y3 = sin(x0.5); figure plot(x,y1,x,y2,'',x,y3,':')
MATLAB® cycles the line color through the default color order.
Specify Line Style, Color, and Marker
Plot three sine curves with a small phase shift between each line. Use a green line with no markers for the first sine curve. Use a blue dashed line with circle markers for the second sine curve. Use only cyan star markers for the third sine curve.
x = 0:pi/10:2*pi; y1 = sin(x); y2 = sin(x0.25); y3 = sin(x0.5); figure plot(x,y1,'g',x,y2,'bo',x,y3,'c*')
Display Markers at Specific Data Points
Create a line plot and display markers at every fifth data point by specifying a marker symbol and setting the MarkerIndices
property as a namevalue pair.
x = linspace(0,10); y = sin(x); plot(x,y,'o','MarkerIndices',1:5:length(y))
Specify Line Width, Marker Size, and Marker Color
Create a line plot and use the LineSpec
option to specify a dashed green line with square markers. Use Name,Value
pairs to specify the line width, marker size, and marker colors. Set the marker edge color to blue and set the marker face color using an RGB color value.
x = pi:pi/10:pi; y = tan(sin(x))  sin(tan(x)); figure plot(x,y,'gs',... 'LineWidth',2,... 'MarkerSize',10,... 'MarkerEdgeColor','b',... 'MarkerFaceColor',[0.5,0.5,0.5])
Add Title and Axis Labels
Use the linspace
function to define x
as a vector of 150 values between 0 and 10. Define y
as cosine values of x
.
x = linspace(0,10,150); y = cos(5*x);
Create a 2D line plot of the cosine curve. Change the line color to a shade of bluegreen using an RGB color value. Add a title and axis labels to the graph using the title
, xlabel
, and ylabel
functions.
figure plot(x,y,'Color',[0,0.7,0.9]) title('2D Line Plot') xlabel('x') ylabel('cos(5x)')
Plot Durations and Specify Tick Format
Define t
as seven linearly spaced duration
values between 0 and 3 minutes. Plot random data and specify the format of the duration
tick marks using the 'DurationTickFormat'
namevalue pair argument.
t = 0:seconds(30):minutes(3); y = rand(1,7); plot(t,y,'DurationTickFormat','mm:ss')
Plot Coordinates from a Table
Since R2022a
A convenient way to plot data from a table is to pass the table to the plot
function and specify the variables to plot.
Read weather.csv
as a timetable tbl
. Then display the first three rows of the table.
tbl = readtimetable("weather.csv");
tbl = sortrows(tbl);
head(tbl,3)
Time WindDirection WindSpeed Humidity Temperature RainInchesPerMinute CumulativeRainfall PressureHg PowerLevel LightIntensity ____________________ _____________ _________ ________ ___________ ___________________ __________________ __________ __________ ______________ 25Oct2021 00:00:09 46 1 84 49.2 0 0 29.96 4.14 0 25Oct2021 00:01:09 45 1.6 84 49.2 0 0 29.96 4.139 0 25Oct2021 00:02:09 36 2.2 84 49.2 0 0 29.96 4.138 0
Plot the row times on the xaxis and the RainInchesPerMinute
variable on the yaxis. When you plot data from a timetable, the row times are plotted on the xaxis by default. Thus, you do not need to specify the Time
variable. Return the Line
object as p
. Notice that the axis labels match the variable names.
p = plot(tbl,"RainInchesPerMinute");
To modify aspects of the line, set the LineStyle
, Color
, and Marker
properties on the Line
object. For example, change the line to a red dotted line with point markers.
p.LineStyle = ":"; p.Color = "red"; p.Marker = ".";
Plot Multiple Table Variables on One Axis
Since R2022a
Read weather.csv
as a timetable tbl
, and display the first few rows of the table.
tbl = readtimetable("weather.csv");
head(tbl,3)
Time WindDirection WindSpeed Humidity Temperature RainInchesPerMinute CumulativeRainfall PressureHg PowerLevel LightIntensity ____________________ _____________ _________ ________ ___________ ___________________ __________________ __________ __________ ______________ 25Oct2021 00:00:09 46 1 84 49.2 0 0 29.96 4.14 0 25Oct2021 00:01:09 45 1.6 84 49.2 0 0 29.96 4.139 0 25Oct2021 00:02:09 36 2.2 84 49.2 0 0 29.96 4.138 0
Plot the row times on the xaxis and the Temperature
and PressureHg
variables on the yaxis. When you plot data from a timetable, the row times are plotted on the xaxis by default. Thus, you do not need to specify the Time
variable.
Add a legend. Notice that the legend labels match the variable names.
plot(tbl,["Temperature" "PressureHg"]) legend
Specify Axes for Line Plot
Starting in R2019b, you can display a tiling of plots using the tiledlayout
and nexttile
functions. Call the tiledlayout
function to create a 2by1 tiled chart layout. Call the nexttile
function to create an axes object and return the object as ax1
. Create the top plot by passing ax1
to the plot
function. Add a title and yaxis label to the plot by passing the axes to the title
and ylabel
functions. Repeat the process to create the bottom plot.
% Create data and 2by1 tiled chart layout x = linspace(0,3); y1 = sin(5*x); y2 = sin(15*x); tiledlayout(2,1) % Top plot ax1 = nexttile; plot(ax1,x,y1) title(ax1,'Top Plot') ylabel(ax1,'sin(5x)') % Bottom plot ax2 = nexttile; plot(ax2,x,y2) title(ax2,'Bottom Plot') ylabel(ax2,'sin(15x)')
Modify Lines After Creation
Define x
as 100 linearly spaced values between $$2\pi $$ and $$2\pi $$. Define y1
and y2
as sine and cosine values of x
. Create a line plot of both sets of data and return the two chart lines in p
.
x = linspace(2*pi,2*pi); y1 = sin(x); y2 = cos(x); p = plot(x,y1,x,y2);
Change the line width of the first line to 2. Add star markers to the second line. Use dot notation to set properties.
p(1).LineWidth = 2;
p(2).Marker = '*';
Plot Circle
Plot a circle centered at the point (4,3) with a radius equal to 2. Use axis equal
to use equal data units along each coordinate direction.
r = 2;
xc = 4;
yc = 3;
theta = linspace(0,2*pi);
x = r*cos(theta) + xc;
y = r*sin(theta) + yc;
plot(x,y)
axis equal

(default)  positive value
Marker size, specified as a positive value in points, where 1 point = 1/72 of an inch.
DatetimeTickFormat
— Format for datetime
tick labels
character vector  string
Format for datetime
tick labels, specified as the commaseparated pair
consisting of "DatetimeTickFormat"
and a character
vector or string containing a date format. Use the letters
AZ
and az
to construct a
custom format. These letters correspond to the Unicode^{®} Locale Data Markup Language (LDML) standard for dates. You
can include nonASCII letter characters such as a hyphen, space, or
colon to separate the fields.
If you do not specify a value for "DatetimeTickFormat"
, then
plot
automatically optimizes and updates the
tick labels based on the axis limits.
Example: "DatetimeTickFormat","eeee, MMMM d, yyyy HH:mm:ss"
displays a date

For a complete list of valid letter identifiers, see the Format
property
for datetime arrays.
DatetimeTickFormat
is not a chart line property.
You must set the tick format using the namevalue pair argument when
creating a plot. Alternatively, set the format using the xtickformat
and ytickformat
functions.
The TickLabelFormat
property of the datetime
ruler stores the format.
DurationTickFormat
— Format for duration
tick labels
character vector  string
Format for duration
tick labels, specified as the commaseparated pair
consisting of "DurationTickFormat"
and a character
vector or string containing a duration format.
If you do not specify a value for "DurationTickFormat"
, then
plot
automatically optimizes and updates the
tick labels based on the axis limits.
To display a duration as a single number that includes a fractional part, for example, 1.234 hours, specify one of the values in this table.
Value of DurationTickFormat  Description 

"y"  Number of exact fixedlength years. A fixedlength year is equal to 365.2425 days. 
"d"  Number of exact fixedlength days. A fixedlength day is equal to 24 hours. 
"h"  Number of hours 
"m"  Number of minutes 
"s"  Number of seconds 
Example: "DurationTickFormat","d"
displays duration values in terms of
fixedlength days.
To display a duration in the form of a digital timer, specify one of these values.
"dd:hh:mm:ss"
"hh:mm:ss"
"mm:ss"
"hh:mm"
In addition, you can display up to nine fractional
second digits by appending up to nine S
characters.
Example: "DurationTickFormat","hh:mm:ss.SSS"
displays the milliseconds of a
duration value to three digits.
DurationTickFormat
is not a chart line property.
You must set the tick format using the namevalue pair argument when
creating a plot. Alternatively, set the format using the xtickformat
and ytickformat
functions.
The TickLabelFormat
property of the duration
ruler stores the format.
Tips
Use
NaN
andInf
values to create breaks in the lines. For example, this code plots the first two elements, skips the third element, and draws another line using the last two elements:plot([1,2,NaN,4,5])
plot
uses colors and line styles based on theColorOrder
andLineStyleOrder
properties of the axes.plot
cycles through the colors with the first line style. Then, it cycles through the colors again with each additional line style.You can change the colors and the line styles after plotting by setting the
ColorOrder
orLineStyleOrder
properties on the axes. You can also call thecolororder
function to change the color order for all the axes in the figure. (since R2019b)
Extended Capabilities
Tall Arrays
Calculate with arrays that have more rows than fit in memory.
Usage notes and limitations:
Supported syntaxes for tall arrays
X
andY
are:plot(X,Y)
plot(Y)
plot(___,LineSpec)
plot(___,Name,Value)
plot(ax,___)
X
must be in monotonically increasing order.Categorical inputs are not supported.
Tall inputs must be real column vectors.
With tall arrays, the
plot
function plots in iterations, progressively adding to the plot as more data is read. During the updates, a progress indicator shows the proportion of data that has been plotted. Zooming and panning is supported during the updating process, before the plot is complete. To stop the update process, press the pause button in the progress indicator.
For more information, see Visualization of Tall Arrays.
GPU Arrays
Accelerate code by running on a graphics processing unit (GPU) using Parallel Computing Toolbox™.
Usage notes and limitations:
This function accepts GPU arrays, but does not run on a GPU.
For more information, see Run MATLAB Functions on a GPU (Parallel Computing Toolbox).
Distributed Arrays
Partition large arrays across the combined memory of your cluster using Parallel Computing Toolbox™.
Usage notes and limitations:
This function operates on distributed arrays, but executes in the client MATLAB.
For more information, see Run MATLAB Functions with Distributed Arrays (Parallel Computing Toolbox).
Version History
Introduced before R2006aR2022b: Plots created with tables preserve special characters in axis and legend labels
When you pass a table and one or more variable names to the plot
function, the axis and legend labels now display any special characters that are included in the table variable names, such as underscores. Previously, special characters were interpreted as TeX or LaTeX characters.
For example, if you pass a table containing a variable named Sample_Number
to the plot
function, the underscore appears in the axis and
legend labels. In R2022a and earlier releases, the underscores are interpreted as
subscripts.
Release  Label for Table Variable "Sample_Number" 

R2022b 

R2022a 

To display axis and legend labels with TeX or LaTeX formatting, specify the labels manually.
For example, after plotting, call the xlabel
or
legend
function with the desired label strings.
xlabel("Sample_Number") legend(["Sample_Number" "Another_Legend_Label"])
R2022a: Pass tables directly to plot
Create plots by passing a table to the plot
function followed by the variables you want to plot. When you specify your data as a table, the axis labels and the legend (if present) are automatically labeled using the table variable names.
