Description

Vector and Matrix Data

example

scatter3(X,Y,Z)displays circles at the locations specified byX,Y, andZ。

To plot one set of coordinates, specifyX,Y, andZas vectors of equal length.
To plot multiple sets of coordinates on the same set of axes, specify at least one ofX,Y, orZas a matrix.(Since R2022a)

example

scatter3(X,Y,Z,S)specifies the circle sizes.

To vary the circle sizes, specifySas a vector.
To specify different sizes across multiple sets of coordinates, specify a matrix.(Since R2022a)

example

scatter3(X,Y,Z,S,C)specifies the circle colors. You can specify one color for all the circles, or you can vary the color. For example, you can plot all red circles by specifyingCas"red"。

example

scatter3(___,'filled')fills in the circles, using any of the input argument combinations in the previous syntaxes.

example

scatter3(___,markertype)specifies the marker type.

Table Data

example

scatter3(tbl,xvar,yvar,zvar)plots the variablesxvar,yvar, andzvarfrom the tabletbl。To plot one data set, specify one variable each forxvar,yvar, andzvar。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.(Since R2021b)

example

scatter3(tbl,xvar,yvar,zvar,'filled')plots the specified variables from the table with filled circles.(Since R2021b)

Additional Options

example

scatter3(ax,___)plots into the axes specified byaxinstead of into the current axes (gca). Theaxoption can precede any of the input argument combinations in the previous syntaxes.

example

scatter3(___,Name,Value)modifies the scatter plot using one or more name-value arguments to set properties. For example:

scatter3(x,y,z,'LineWidth',2)creates a scatter plot with 2-point marker outlines.
scatter3(tbl,'MyX','MyY','MyZ','ColorVariable','MyColors')creates a scatter plot from data in a table, and customizes the marker colors using data from the table.

For a full list of properties, seeScatter Properties。

example

h= scatter3(___)returns theScatterobject. Usehto modify properties of the scatter chart after it is created.

Plot Data from a Table

Open Live Script

Since R2021b

A convenient way to plot data from a table is to pass the table to thescatter3function and specify the variables you want to plot. For example, readpatients.xlsas a tabletbl。Plot the relationship between theSystolic,Diastolic, andWeightvariables by passingtblas the first argument to thescatter3function followed by the variable names. By default, the axis labels match the variable names.

tbl = readtable('patients.xls');scatter3(tbl,'Systolic','Diastolic','Weight');

Figure contains an axes object. The axes object contains an object of type scatter.

You can also plot multiple variables at the same time. For example, plot both blood pressure variables on thex-axis by specifying thexvarargument as the cell array{'Systolic','Diastolic'}。Then add a legend. The legend labels match the variable names.

scatter3(tbl,{'Systolic','Diastolic'},'Age','Weight');传说

Figure contains an axes object. The axes object contains 2 objects of type scatter.

Plot Table Data with Custom Marker Sizes and Colors

Open Live Script

Since R2021b

One way to plot data from a table and customize the colors and marker sizes is to set theColorVariableandSizeDataproperties. You can set these properties as name-value arguments when you call thescatter3function, or you can set them on theScatterobject later.

例如,readpatients.xlsas a tabletbl。Plot the relationship between theSystolic,Diastolic, andWeightvariables with filled markers. Vary the marker colors by specifying theColorVariablename-value argument. Return theScatterobject ass, so you can set other properties later.

tbl = readtable('patients.xls');s = scatter3(tbl,'Systolic','Diastolic','Weight','filled',。..'ColorVariable','Diastolic');

Multiple sets of points that are different colors	If all the data sets share coordinates in one or more dimensions, specify the shared coordinates as a vector and the other coordinates as matrices. The length of the vector must match one of the dimensions of the matrices. For example, plot two data sets that share the samex-coordinates.

`C`- - - - - -Marker color
color name|RGB triplet|matrix of RGB triplets|vector of colormap indices

标志的颜色,颜色名称,指定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 theX,Y, andZvectors.

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`"red"`。 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`[1 0 0]`。 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`X`,`Y`, and`Z`are vectors, and`S`is either a vector or a scalar.	Create a vector`C`that specifies four colormap indices. Plot four points using the colors from the current colormap. Then, change the colormap to`winter`。 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")
fo创建一个自定义颜色r each point.	Specify an m-by-3 matrix of RGB triplets, where m is the number of points in the plot. You can use this method only when`X`,`Y`, and`Z`are vectors, and`S`is either a vector or a scalar.	Create a matrix`C`that specifies RGB triplets for green, red, gray, and purple. Then create a scatter plot of four points using those colors. 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 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`X`,`Y`,`Z`, or`S`is a matrix.	Create a matrix`C`that contains two RGB triplets. Then plot two data sets using those colors. 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)

`'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 theCData财产。

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 character vector or a string scalar that starts with a hash symbol (#) followed by three or six hexadecimal digits, which can range from0toF。The values are not case sensitive. Thus, 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.

Specifying Color Data

Specifying theColorVariableproperty controls the colors of the markers. The data in the variable controls the marker fill color when theMarkerFaceColorproperty is set to'flat'。The data can also control the marker outline color, when theMarkerEdgeColoris 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 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]。例如,[0.5 0.7 1]specifies a shade of light blue.

When you set theColorVariableproperty, MATLAB updates theCData财产。
