Syntax
ts = textscatter3(x,y,z,str)
ts = textscatter3(xyz,str)
ts = textscatter3(ax,___)
ts = textscatter3(___,Name,Value)
Description
example
ts = textscatter3(x,y,z,str) creates a 3-D text scatter plot with elements of str at the locations specified by the vectors x, y, and z.
example
ts = textscatter3(xyz,str) creates a 3-D text scatter plot with elements of str at the locations specified by the rows of xyz. This syntax is equivalent to textscatter(xyz(:,1),xyz(:,2),xyz(:,3),str).
ts = textscatter3(ax,___) plots into axes object ax. Use this syntax with any of the input arguments in previous syntaxes.
example
ts = textscatter3(___,Name,Value) specifies additional TextScatter properties using one or more name-value pair arguments.

Create 3-D Text Scatter Plot
Open Live Script
Plot a string array of numbers at random points on a 3-D text scatter plot.
x = rand(50,1);y = rand(50,1);z = rand(50,1);str = string(1:50);figuretextscatter3(x,y,z,str);
Alternatively, you can pass the coordinates x, y, and z as a matrix xyz, where x, y, and z are the columns of xyz.
xyz = [x y z];figuretextscatter3(xyz,str)
Specify Word Colors
Open Live Script
Create text scatter plot of a word embedding and specify word colors.
Load a pretrained word embedding using fastTextWordEmbedding. This function requires Text Analytics Toolbox™ Model for fastText English 16 Billion Token Word Embedding support package. If this support package is not installed, then the function provides a download link.
emb = fastTextWordEmbedding;
Convert the first 250 words to vectors using word2vec. V is a matrix of word vectors of length 300.
words = emb.Vocabulary(1:250);V = word2vec(emb,words);size(V)
ans = 1×2 250 300Embed the word vectors in a 3-D space using tsne.
XYZ = tsne(V,'NumDimensions',3);Plot the words at the coordinates specified by XYZ in a 3-D text scatter plot. Specify the word colors to be random.
numWords = numel(words);colorData = rand(numWords,3);figuretextscatter3(XYZ,words,'ColorData',colorData)title("Word Embedding t-SNE Plot")
Input Arguments
collapse all
x — x values
vector
x values, specified as a vector. x, y, z, and str must be of equal length.
Example: [1 2 3]
y — y values
vector
y values, specified as a vector. x, y, z, and str must be of equal length.
Example: [1 2 3]
z — z values
vector
z values, specified as a vector. x, y, z, and str must be of equal length.
Example: [1 2 3]
xyz — x, y, and z values
matrix
x, y, and z values, specified as a matrix. The first, second, and third columns of xyz correspond to the x, y, and z values, respectively.
str — Input text
string vector | cell array of character vectors
Input text, specified as a string vector or cell array of character vectors. x, y, z, and str must be of equal length.
Example: ["one" "two" "three"]
Data Types: string | cell
ax — Axes object
axes object
Axes object. If you do not specify an axes object, then the function uses the current axes.
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: 'Marker','*' specifies the markers to be asterisks.
The TextScatter object properties listed here are only a subset. For a complete list, see TextScatter Properties.
TextDensityPercentage — Percentage of text data to show
60 (default) | scalar from 0 through 100
Percentage of text data to show, specified as a scalar from 0 through 100. To show all text, set TextDensityPercentage to 100. To show no text, set TextDensityPercentage to 0.
If you set TextDensityPercentage to 100, then the software does not plot markers.
Example: 70
MaxTextLength — Maximum length of text labels
40 (default) | positive integer
Maximum length of text labels, specified as a positive integer. The software truncates the text labels to this length and adds ellipses at the point of truncation.
Example: 10
MarkerColor — Marker colors
'auto' (default) | 'none' | RGB triplet
Marker colors, specified as one of these values:
'auto'— For each marker, use the same color as the corresponding text labels.'none'— Do not show markers.RGB triplet — Use the same color for all the markers in the plot. 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,[0.5 0.6 0.7].
Example: [1 0 0]
ColorData — Text colors
[] (default) | RGB triplet | matrix of RGB triplets | categorical vector
Text colors, specified as one of these values:
RGB triplet — Use the same color for all the text in the plot. 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,[0.5 0.6 0.7].Three-column matrix of RGB triplets — Use a different color for each text label in the plot. Each row of the matrix defines one color. The number of rows must equal the number of text labels.
Categorical vector — Use a different color for each category in the vector. Specify
ColorDataas a vector the same length asXData. Specify the colors for each category using theColorsproperty
Example: [1 0 0; 0 1 0; 0 0 1]
Colors — Category colors
matrix of RGB triplets
Category colors, specified as a matrix of RGB triplets. 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, [0.5 0.6 0.7].
By default, Colors is equal to the ColorOrder property of the axes object.
Example: [1 0 0; 0 1 0; 0 0 1]
Output Arguments

ts — TextScatter object
TextScatter object
TextScatter object. Use ts to access and modify properties of the text scatter chart after it has been created. For more information, see TextScatter Properties.
