Syntax
Description
Vector and Matrix Data
polarbubblechart(
displays colored circular markers (bubbles) at the locations specified by the vectors
theta
,rho
,sz
)theta
and rho
. The bubble sizes are specified by
sz
.
To plot one set of coordinates, specify
theta
,rho
, andsz
as vectors of equal length.To plot multiple sets of coordinates on the same set of axes, specify at least one of
theta
,rho
, orsz
as a matrix.
Table Data
polarbubblechart(
plots the variables tbl
,thetavar
,rhovar
,sizevar
)thetavar
and rhovar
from the
table tbl
and uses the variable sizevar
for the
bubble sizes. To plot one data set, specify one variable each for
thetavar
, rhovar
, and sizevar
.
To plot multiple data sets, specify multiple variables for at least one of those
arguments. The arguments that specify multiple variables must specify the same number of
variables.
Additional Options

,___)pax
. Specify the axes
before all other input arguments.
polarbubblechart(___,
specifies Name,Value
)BubbleChart
properties using one or more name-value
arguments. Specify the properties after all other input arguments. For a list of
properties, see BubbleChart Properties.
bc = polarbubblechart(___)
returns the
BubbleChart
object. Use bc
to modify properties of
the chart after creating it. For a list of properties, see BubbleChart Properties.
Examples
Plot Random Bubbles
Define a set of bubble coordinates as the vectors th
and r
. Define sz
as a vector of bubble sizes. Then create a bubble chart of these values.
th = linspace(0,2*pi,10); r = rand(1,10); sz = rand(1,10); polarbubblechart(th,r,sz);
Specify Bubble Colors
Define a set of bubble coordinates as the vectors th
and r
. Define sz
as a vector of bubble sizes. Then create a bubble chart and specify the color as red. By default, the bubbles are partially transparent.
th = 1:10;
r = rand(1,10);
sz = rand(1,10);
polarbubblechart(th,r,sz,'red');
For a custom color, you can specify an RGB triplet or a hexadecimal color code. For example, the hexadecimal color code '#7031BB'
, specifies a shade of purple.
polarbubblechart(th,r,sz,'#7031BB');
You can also specify a different color for each bubble. For example, specify a vector to select colors from the figure's colormap.
c = 1:10; polarbubblechart(th,r,sz,c)
Specify Bubble Transparency and Outline Color
Define a set of bubble coordinates as the vectors th
and r
. Define sz
as a vector of bubble sizes. Then create a bubble chart. By default, the bubbles are 60% opaque, and the edges are completely opaque with the same color.
th = linspace(0,2*pi,10); r = rand(1,10); sz = rand(1,10); polarbubblechart(th,r,sz);
You can customize the opacity and the outline color by setting the MarkerFaceAlpha
and MarkerEdgeColor
properties, respectively. One way to set a property is by specifying a name-value pair argument when you create the chart. For example, you can specify 20% opacity by setting the MarkerFaceAlpha
value to 0.20
.
bc = polarbubblechart(th,r,sz,'MarkerFaceAlpha',0.20);
If you create the chart by calling the polarbubblechart
function with a return argument, you can use the return argument to set properties on the chart after creating it. For example, you can change the outline color to purple.
bc.MarkerEdgeColor = [0.5 0 0.5];
Add a Bubble Legend
Define a data set that shows the incoming air traffic at a certain airport over a certain period of time.
Define
theta
as a vector of angles of approach for the incoming planes.Define
altitude
as a vector of altitudes.Define
planesize
as a vector of plane sizes, measured in the number of passengers.
Then display the data in a bubble chart with a bubble legend that shows the relationship between the bubble sizes and the number of passengers on the planes.
theta = repmat([0 pi/2 7*pi/6],1,4) + 0.25*randn(1,12); altitude = randi([13000 43000],1,12); planesize = randi([75 500],[1 12]); polarbubblechart(theta,altitude,planesize) bubblelegend('Number of Passengers','Location','eastoutside')
Plot Data from a Table
A convenient way to plot data from a table is to pass the table to the polarbubblechart
function and specify the variables you want to plot. For example, create a table with four variables. Plot the 'Th'
and 'R1'
variables, and vary the bubble sizes according to the 'Sz'
variable.
% Create a table of random numbers Th = linspace(0,2*pi,10)'; R1 = randi([0 10],10,1); R2 = randi([20 30],10,1); Sz = rand(10,1); tbl = table(Th,R1,R2,Sz); % Create polar bubble chart polarbubblechart(tbl,'Th','R1','Sz')
You can also plot multiple variables at the same time. For example, plot two sets of radius values by specifying the rhovar
argument as the cell array {'R1','R2'}
. Then add a legend. The legend labels match the variable names.
polarbubblechart(tbl,'Th',{'R1','R2'},'Sz') legend
Plot Table Data with Custom Colors
You can plot data from a table and customize the colors by specifying the cvar
argument when you call the polarbubblechart
function.
For example, create a table with four variables of random numbers, and plot the Th
and R
variables. Vary the bubble sizes according to the Sz
variable, and vary the colors according to the Colors
variable.
% Create a table of random numbers Th = linspace(0,2*pi,10)'; R = randi([0 10],10,1); Sz = rand(10,1); Colors = rand(10,1); tbl = table(Th,R,Sz,Colors); % Create polar bubble chart polarbubblechart(tbl,'Th','R','Sz','Colors')
Display Bubbles in Different Axes on the Same Scale
Define two data sets showing the incoming air traffic at two different airports over a certain period of time.
Define
theta1
andtheta2
as vectors containing the angles of approach for the incoming planes.Define
planesize1
andplanesize2
as a vectors of plane sizes, measured in the number of passengers.Define
altitude1
andaltitude2
as vectors containing the altitudes for the planes.
theta1 = repmat([0 pi/2 7*pi/6],1,4) + 0.25*randn(1,12); theta2 = repmat([pi pi/6 3*pi/2],1,4) + 0.25*randn(1,12); planesize1 = randi([75 500],[1 12]); planesize2 = randi([1 50],[1 12]); altitude1 = randi([13000 43000],1,12); altitude2 = randi([13000 85000],1,12);
Create a tiled chart layout so you can visualize the data side-by-side. Then, create a polar axes object in the first tile, plot the data for the first airport, and add a title. Then repeat the process in the second tile for the second airport.
t = tiledlayout(1,2); pax1 = polaraxes(t); polarbubblechart(pax1,theta1,altitude1,planesize1) title('Airport A') pax2 = polaraxes(t); pax2.Layout.Tile = 2; polarbubblechart(pax2,theta2,altitude2,planesize2); title('Airport B')
Reduce all the bubble sizes to make it easier to see all the bubbles. In this case, change the range of diameters to be between 5
and 20
points.
bubblesize(pax1,[5 20]) bubblesize(pax2,[5 20])
The planes at Airport A are generally much smaller than at Airport B, but the bubble sizes do not reflect this information in the preceding charts. This is because the smallest and largest bubbles map to the smallest and largest data points in each of the axes. To display the bubbles on the same scale, define a vector called allsizes
that includes the plane sizes at both airports. Then use the bubblelim
function to reset the scaling for both charts.
allsizes = [planesize1 planesize2]; newlims = [min(allsizes) max(allsizes)]; bubblelim(pax1,newlims) bubblelim(pax2,newlims)

c
— Bubble color
[0 0.4470 0.7410]
(default) | color name | RGB triplet | matrix of RGB triplets | vector of colormap indices
Bubble 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 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]
. RGB triplets are useful for creating custom colors.Matrix of RGB triplets — A three-column 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
theta
andrho
vectors.
The way you specify the color depends on your preferred color scheme and whether you are plotting one set of bubbles or multiple sets of bubbles. This table describes the most common situations.
Color Scheme | How to Specify the Color | Example |
---|---|---|
Use one color for all the bubbles. | Specify a color name or a short name from the table below, or specify one RGB triplet. | Display one set of bubbles, and specify the color as
theta = [0 pi/4 pi/3 pi/2];
rho = [1 2 3 4];
sz = [10 20 30 40];
polarbubblechart(theta,rho,sz,'red') Display
two sets of bubbles, and specify the color as red using the RGB triplet
theta = [0 pi/4 pi/3 pi/2]; rho = [1 5; 2 6; 3 7; 4 8]; sz = [10 20; 30 40; 50 60; 70 80]; polarbubblechart(theta,rho,sz,[1 0 0]) |
Assign different colors to each bubble 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 chart has three bubbles, 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];
theta = [0 pi/4 pi/3 pi/2];
rho = [1 2 3 4];
sz = [10 20 30 40];
polarbubblechart(theta,rho,sz,c)
colormap(gca,"winter") |
Create a custom color for each bubble. | Specify an m-by-3 matrix of RGB triplets, where m is the number of bubbles. 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]; theta = [0 pi/4 pi/3 pi/2]; rho = [1 2 3 4]; sz = [10 20 30 40]; polarbubblechart(theta,rho,sz,c) |
Create a different color for each data set. | Specify an n-by-3 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]; theta = [0 pi/4 pi/3 pi/2]; rho = [1 5; 2 6; 3 7; 4 8]; sz = [10 20; 30 40; 50 60; 70 80]; polarbubblechart(theta,rho,sz,c) |

Plotting Your Data
The table variables you specify can contain any numeric data type.
To plot one data set, specify one variable each for thetavar
,
rhovar
, sizevar
, and optionally
cvar
. For example, create a table with four variables. Plot the
Th
and R1
variables, and vary the bubble sizes
according to the Sz
variable.
% Create a table of random numbers Th = linspace(0,2*pi,10)'; R1 = randi([0 10],10,1); R2 = randi([20 30],10,1); Sz = rand(10,1); tbl = table(Th,R1,R2,Sz); % Create polar bubble chart polarbubblechart(tbl,'Th','R1','Sz')
To plot multiple data sets together, specify multiple variables for at least one of
thetavar
, rhovar
, sizevar
, or
optionally cvar
. 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 Th
variable on the theta-axis and
the R1
and R2
variables on the
r-axis. Specify the Sz
variable for the bubble
sizes.
polarbubblechart(tbl,'Th',{'R1','R2'},'Sz')
You can also use different indexing schemes for the table variables. For example, specify thetavar
as a variable name, rhovar
as an index number, and sizevar
as a logical vector.
polarbubblechart(tbl,'Th',2,[false false true])
rhovar
— Table variables containing rho values
one or more table variable indices
Table variables containing the rho values, specified as one or more table variable indices.

thetavar
, rhovar
, sizevar
, or

variable on the theta-axis and
the R1
and R2
variables on the
r-axis. Specify the Sz
variable for the bubble
sizes.
polarbubblechart(tbl,'Th',{'R1','R2'},'Sz')
You can also use different indexing schemes for the table variables. For example, specify thetavar
as a variable name, rhovar
as an index number, and sizevar
as a logical vector.
polarbubblechart(tbl,'Th',2,[false false true])
sizevar
— Table variables for bubble sizes
one or more table variable indices
Table variables containing the bubble size data, specified as one or more table variable indices.

If you are plotting one data set, specify one variable for
sizevar
. For example, create a table with four variables. Plot
the Th
and R
variables, and vary the bubble
sizes according to the Sz1
variable.
% Create a table of random numbers Th = linspace(0,2*pi,10)'; R = randi([0 10],10,1); Sz1 = rand(10,1); Sz2 = rand(10,1); tbl = table(Th,R,Sz1,Sz2); % Create polar bubble chart polarbubblechart(tbl,'Th','R','Sz1')
If you are plotting multiple data sets, you can specify multiple variables for at
least one of thetavar
, rhovar
,
sizevar
, or optionally cvar
. 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 Th
variable on the
theta-axis and the R
variable on the
r-axis. Specify the Sz1
and
Sz2
variables for the bubble sizes. The resulting plot shows two
sets of bubbles with the same coordinates, but different bubble
sizes.
polarbubblechart(tbl,'Th','R',{'Sz1','Sz2'})
cvar
— Table variables for bubble colors
one or more table variable indices
Table variables containing the bubble color data, specified as one or more table variable indices.

---|---|
Variable names:
|
|

|
Plotting Your Data
The table variables you specify can contain values of any numeric type. Each variable can be:
A column of numbers that linearly map into the current colormap.
A three-column array of RGB triplets. RGB triplets are three-element 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.
If you are plotting one data set, specify one variable for
cvar
. For example, create a table with six variables of random
numbers. Plot the Th
and R1
variables. Vary the
bubble sizes according to the Sz
variable, and vary the colors
according to the Color1
variable.
% Create a table of random numbers Th = linspace(0,2*pi,10)'; R1 = randi([0 10],10,1); R2 = randi([20 30],10,1); Sz = rand(10,1); Color1 = rand(10,1); Color2 = rand(10,1); tbl = table(Th,R1,R2,Sz,Color1,Color2); % Create polar bubble chart polarbubblechart(tbl,'Th','R1','Sz','Color1')
If you are plotting multiple data sets, you can specify multiple variables for at
least one of thetavar
, rhovar
,
sizevar
, or cvar
. 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 Th
variable on the
theta-axis and the R1
and
R2
variables on the r-axis. Vary the bubble
sizes according to the Sz
variable. Specify the
Color1
and Color2
variables for the colors.
The resulting plot shows two sets of bubbles with the same
theta-coordinates and bubble sizes, but different
r-coordinates and
colors.
polarbubblechart(tbl,'Th',{'R1','R2'},'Sz',{'Color1','Color2'})
pax
— Target axes
PolarAxes
object
Target axes, specified as a PolarAxes
object. If you do not
specify the axes, MATLAB plots into the current axes, or it creates a PolarAxes
object if one does not exist.
Name-Value Arguments
Specify optional pairs of arguments as
Name1=Value1,...,NameN=ValueN
, where Name
is
the argument name and Value
is the corresponding value.
Name-value arguments must appear after other arguments, but the order of the
pairs does not matter.
Before R2021a, use commas to separate each name and value, and enclose
Name
in quotes.
Example: bubblechart([1 2 3],[4 10 9],[1 2 3],'MarkerFaceColor','red')
creates red bubbles.
Note
The properties listed here are only a subset. For a complete list, see BubbleChart Properties.
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 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 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.
Color Name | Short Name | RGB Triplet | Hexadecimal Color Code | Appearance |

MarkerFaceColor
— Marker fill color
'flat'
(default) | 'auto'
| 'none'
| 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 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 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.
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" | |

LineWidth
— Width of marker edge
0.5
(default) | positive value
Width of marker edge, specified as a positive value in point units.
Example: 0.75
MarkerEdgeAlpha
— Marker edge transparency
1
(default) | scalar in range [0,1]
| 'flat'
Marker edge transparency, specified as a scalar in the range [0,1]
or 'flat'
. A value of 1 is opaque and 0 is completely transparent.
Values between 0 and 1 are semitransparent.
To set the edge transparency to a different value for each point in the plot, set the
AlphaData
property to a vector the same size as the
XData
property, and set the
MarkerEdgeAlpha
property to 'flat'
.
MarkerFaceAlpha
— Marker face transparency
0.6
(default) | scalar in range [0,1]
| 'flat'
Marker face transparency, specified as a scalar in the range [0,1]
or 'flat'
. A value of 1 is opaque and 0 is completely transparent. Values between 0 and 1 are partially transparent.
To set the marker face transparency to a different value for each point, set the AlphaData
property to a vector the same size as the XData
property, and set the MarkerFaceAlpha
property to 'flat'
.
Version History
Introduced in R2020bR2022b: Plots created with tables preserve special characters in legend labels
When you pass a table and one or more variable names to the polarbubblechart
function, the 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 polarbubblechart
function and then display a legend, the
underscore appears in the legend label. In R2022a and earlier releases, the
underscore is interpreted as a subscript.
Release | Label for Table Variable "Sample_Number" |
---|---|
R2022b |
|
R2022a |
|
To display legend labels with TeX or LaTeX formatting, call the legend
function with the desired label strings after plotting. For example:
legend(["Sample_Number" "Another_Legend_Label"])
R2022a: Plot multiple data sets at once using matrices
The polarbubblechart
function now accepts combinations of vectors and matrices for the coordinates and size data. 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 polarbubblechart
Create plots by passing a table to the polarbubblechart
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.
