Examples
Create 3D Scatter Plot
Create a 3D scatter plot. Use sphere
to define vectors x
, y
, and z
.
figure [X,Y,Z] = sphere(16); x = [0.5*X(:); 0.75*X(:); X(:)]; y = [0.5*Y(:); 0.75*Y(:); Y(:)]; z = [0.5*Z(:); 0.75*Z(:); Z(:)]; scatter3(x,y,z)
Vary Marker Size
Use sphere
to define vectors x
, y
, and z
.
[X,Y,Z] = sphere(16); x = [0.5*X(:); 0.75*X(:); X(:)]; y = [0.5*Y(:); 0.75*Y(:); Y(:)]; z = [0.5*Z(:); 0.75*Z(:); Z(:)];
Define vector s
to specify the marker sizes.
S = repmat([100,50,5],numel(X),1); s = S(:);
Create a 3D scatter plot and use view
to change the angle of the axes in the figure.
figure scatter3(x,y,z,s) view(40,35)
Corresponding entries in x
, y
, z
, and s
determine the location and size of each marker.
Vary Marker Color
Use sphere
to define vectors x
, y
, and z
.
[X,Y,Z] = sphere(16); x = [0.5*X(:); 0.75*X(:); X(:)]; y = [0.5*Y(:); 0.75*Y(:); Y(:)]; z = [0.5*Z(:); 0.75*Z(:); Z(:)];
Define vectors s
and c
to specify the size and color of each marker.
S = repmat([50,25,10],numel(X),1); C = repmat([1,2,3],numel(X),1); s = S(:); c = C(:);
Create a 3D scatter plot and use view
to change the angle of the axes in the figure.
figure scatter3(x,y,z,s,c) view(40,35)
Corresponding entries in x
, y
, z
, and c
determine the location and color of each marker.
Fill in Markers
Create vectors x
and y
as cosine and sine values with random noise.
z = linspace(0,4*pi,250); x = 2*cos(z) + rand(1,250); y = 2*sin(z) + rand(1,250);
Create a 3D scatter plot and fill in the markers. Use view
to change the angle of the axes in the figure.
scatter3(x,y,z,'filled')
view(30,10)
Set Marker Type
Initialize the randomnumber generator to make the output of rand
repeatable. Define vectors x
and y
as cosine and sine values with random noise.
rng default
z = linspace(0,4*pi,250);
x = 2*cos(z) + rand(1,250);
y = 2*sin(z) + rand(1,250);
Create a 3D scatter plot and set the marker type. Use view
to change the angle of the axes in the figure.

Set Marker Properties
Initialize the randomnumber generator to make the output of rand
repeatable. Define vectors x
and y
as cosine and sine values with random noise.
rng default
z = linspace(0,4*pi,250);
x = 2*cos(z) + rand(1,250);
y = 2*sin(z) + rand(1,250);
Create a 3D scatter plot and set the marker edge color and the marker face color. Use view
to change the angle of the axes in the figure.
figure scatter3(x,y,z,... 'MarkerEdgeColor','k',... 'MarkerFaceColor',[0 .75 .75]) view(30,10)
Plot Data from a Table
Since R2021b
A convenient way to plot data from a table is to pass the table to the scatter3
function and specify the variables you want to plot. For example, read patients.xls
as a table tbl
. Plot the relationship between the Systolic
, Diastolic
, and Weight
variables by passing tbl
as the first argument to the scatter3
function followed by the variable names. By default, the axis labels match the variable names.
tbl = readtable('patients.xls'); scatter3(tbl,'Systolic','Diastolic','Weight');
You can also plot multiple variables at the same time. For example, plot both blood pressure variables on the xaxis by specifying the xvar
argument as the cell array {'Systolic','Diastolic'}
. Then add a legend. The legend labels match the variable names.
scatter3(tbl,{'Systolic','Diastolic'},'Age','Weight'); legend
Plot Table Data with Custom Marker Sizes and Colors
Since R2021b
One way to plot data from a table and customize the colors and marker sizes is to set the ColorVariable
and SizeData
properties. You can set these properties as namevalue arguments when you call the scatter3
function, or you can set them on the Scatter
object later.
For example, read patients.xls
as a table tbl
. Plot the relationship between the Systolic
, Diastolic
, and Weight
variables with filled markers. Vary the marker colors by specifying the ColorVariable
namevalue argument. Return the Scatter
object as s
, so you can set other properties later.
tbl = readtable('patients.xls'); s = scatter3(tbl,'Systolic','Diastolic','Weight','filled', ... 'ColorVariable','Diastolic');
Change the marker sizes to 100 points by setting the SizeData
property. Then add a colorbar.
s.SizeData = 100; colorbar
Specify Axes for 3D Scatter Plot
You can display a tiling of plots using the tiledlayout
and nexttile
functions.
Load the seamount
data set to get vectors x
, y
, and z
. Call the tiledlayout
function to create a 2by1 tiled chart layout. Call the nexttile
function to create the axes objects ax1
and ax2
. Then create separate scatter plots in the axes by specifying the axes object as the first argument to scatter3
.
load seamount tiledlayout(2,1) ax1 = nexttile; ax2 = nexttile; scatter3(ax1,x,y,z,'MarkerFaceColor',[0 .75 .75]) scatter3(ax2,x,y,z,'*')
Set Scatter Series Properties Using Handle
Use the sphere
function to create vectors x
, y
, and z
.
[X,Y,Z] = sphere(16); x = [0.5*X(:); 0.75*X(:); X(:)]; y = [0.5*Y(:); 0.75*Y(:); Y(:)]; z = [0.5*Z(:); 0.75*Z(:); Z(:)];
Create vectors s
and c
to specify the size and color for each marker.
S = repmat([70,50,20],numel(X),1); C = repmat([1,2,3],numel(X),1); s = S(:); c = C(:);
Create a 3D scatter plot and return the scatter series object.
h = scatter3(x,y,z,s,c);
Use an RGB triplet color value to set the marker face color. Use dot notation to set properties.
h.MarkerFaceColor = [0 0.5 0.5];

C
— Marker color
color name  RGB triplet  matrix of RGB triplets  vector of colormap indices
Marker color, specified as a color name, RGB triplet, matrix of RGB triplets, or a vector of colormap indices.
Color name — A color name such as
"red"
, or a short name such as"r"
.RGB triplet — A threeelement 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]
. RGB triplets are useful for creating custom colors.Matrix of RGB triplets — A threecolumn matrix in which each row is an RGB triplet.
Vector of colormap indices — A vector of numeric values that is the same length as the
X
,Y
, andZ
vectors.
The way you specify the color depends on your preferred color scheme and whether you are plotting one set of coordinates or multiple sets of coordinates. This table describes the most common situations.
Color Scheme  How to Specify the Color  Example 

Use one color for all the points.  Specify a color name or a short name from the table below, or specify one RGB triplet.  Plot one set of points, and specify the color
as X = [1 2 3 4];
Y = [2 5 3 6];
Z = [10 6 4 7];
S = 50;
scatter3(X,Y,Z,S,"red") Plot
two sets of points, and specify the color as red
using the RGB triplet X = [1 2 3 4]; Y = [2 5 3 6]; Z = [2 5; 1 2; 8 4; 7 9]; S = 50; scatter3(X,Y,Z,S,[1 0 0]) 
Assign different colors to each point using a colormap.  Specify a row or column vector of numbers. The numbers map into the current colormap array. The smallest value maps to the first row in the colormap, and the largest value maps to the last row. The intermediate values map linearly to the intermediate rows. If your plot has three points, specify a column vector to ensure the values are interpreted as colormap indices. You can use this method only
when  Create a vector C = [1 2 3 4];
X = [1 2 3 4];
Y = [1 0 6 2];
Z = [2 5 3 7];
S = 50;
scatter3(X,Y,Z,S,C)
colormap(gca,"winter") 
Create a custom color for each point.  Specify an mby3 matrix of RGB triplets, where m is the number of points in the plot. You can use this method only when
 Create a matrix C = [0 1 0; 1 0 0; 0.5 0.5 0.5; 0.6 0 1]; X = [1 2 3 4]; Y = [2 5 3 6]; Z = [10 6 4 7]; S = 50; scatter3(X,Y,Z,S,C) 
Create a different color for each data set.  Specify an nby3 matrix of RGB triplets, where n is the number of data sets. You can
use this method only when at least one of
 Create a matrix C = [1 0 0; 0.6 0 1]; X = [1 2 3 4]; Y = [5 6 7 8]; Z = [2 5; 1 2; 8 4; 11 9]; S = 50; scatter3(X,Y,Z,S,C)

'filled'
— Option to fill interior of markers
'filled'
Option to fill the interior of the markers, specified as
'filled'
. Use this option with markers that have a
face, for example, 'o'
or 'square'
.
Markers that do not have a face and contain only edges do not draw
('+'
, '*'
, '.'
,
and 'x'
).
The 'filled'
option sets the
MarkerFaceColor
property of the Scatter
object to 'flat'
and
the MarkerEdgeColor
property to
'none'
, so the marker faces draw, but the edges do
not.

Plotting Your Data
The table variables you specify can contain numeric, categorical, datetime, or duration values.
To plot one data set, specify one variable for xvar
, one variable for
yvar
, and one variable for zvar
. For example, read
Patients.xls
into the table tbl
. Plot the
Height
, Weight
, and Diastolic
variables.
tbl = readtable("Patients.xls"); scatter3(tbl,"Height","Weight","Diastolic")
To plot multiple data sets together, specify multiple variables for at least one of
xvar
, yvar
, or zvar
. If you
specify multiple variables for more than one argument, the number of variables must be the
same for each of those arguments.
For example, plot the Weight
variable on the xaxis, the
Systolic
and Diastolic
variables on the
yaxis, and the Age
variable on the
zaxis.
scatter3(tbl,"Weight",["Systolic","Diastolic"],"Age")
You can also use different indexing schemes for xvar

xvar
as a variable name, yvar
as an index number,
and zvar
as a logical
vector.

— Axes object
axes object
Axes object. If you do not specify an axes, then scatter3
plots
into the current axes.
NameValue Arguments
Specify optional pairs of arguments as
Name1=Value1,...,NameN=ValueN
, where Name
is
the argument name and Value
is the corresponding value.
Namevalue arguments must appear after other arguments, but the order of the
pairs does not matter.

MarkerEdgeColor
— Marker outline color
"flat"
(default)  RGB triplet  hexadecimal color code  "r"
 "g"
 "b"
 ...
Marker outline color, specified "flat"
, an RGB triplet, a hexadecimal color
code, a color name, or a short name. The default value of "flat"
uses
colors from the CData
property.
For a custom color, specify an RGB triplet or a hexadecimal color code.
An RGB triplet is a threeelement 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 string scalar or character vector that starts with a hash symbol (
#
) followed by three or six hexadecimal digits, which can range from0
toF
. The values are not case sensitive. Therefore, 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.

MarkerFaceColor
— Marker fill color
"none"
(default)  "flat"
 "auto"
 RGB triplet  hexadecimal color code  "r"
 "g"
 "b"
 ...
Marker fill color, specified as "flat"
, "auto"
, an RGB
triplet, a hexadecimal color code, a color name, or a short name. The
"flat"
option uses the CData
values. The
"auto"
option uses the same color as the
Color
property for the axes.
For a custom color, specify an RGB triplet or a hexadecimal color code.
An RGB triplet is a threeelement 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 string scalar or character vector that starts with a hash symbol (
#
) followed by three or six hexadecimal digits, which can range from0
toF
. The values are not case sensitive. Therefore, 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.

ColorVariable
— Table variable containing color data
table variable index
Table variable containing the color data, specified as a variable index into the source table.
Specifying the Table Index
Use any of the following indexing schemes to specify the desired variable.
Indexing Scheme  Examples 

Variable name:


Variable index:


Variable type:


Specifying Color Data
Specifying the ColorVariable
property controls the colors of the markers.
The data in the variable controls the marker fill color when the
MarkerFaceColor
property is set to
"flat"
. The data can also control the marker outline color,
when the MarkerEdgeColor
is set to
"flat"
.
The table variable you specify can contain values of any numeric type. The values can be in either of the following forms:
A column of numbers that linearly map into the current colormap.
A threecolumn array of RGB triplets. RGB triplets are threeelement vectors whose values specify the intensities of the red, green, and blue components of specific colors. The intensities must be in the range
[0,1]
. For example,[0.5 0.7 1]
specifies a shade of light blue.
When you set the ColorVariable
property, MATLAB updates the CData
property.
Output Arguments
h
— Scatter
object
Scatter
object
Scatter
object. This is a unique identifier,
which you can use to query and modify the properties of the Scatter
object
after it is created.
Extended Capabilities
GPU Arrays
Accelerate code by running on a graphics processing unit (GPU) using Parallel Computing Toolbox™.
The scatter3
function
supports GPU array input with these 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 scatter3
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 scatter3
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: Plot multiple data sets at once using matrices
The scatter3
function now accepts combinations of vectors
and matrices for the coordinates. As a result, you can visualize multiple data sets
at once rather than using the hold
function between plotting
commands.
R2021b: Pass tables directly to scatter3
Create plots by passing a table to the scatter3
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.
