plot3

3-D point or line plot

  • 3-D line plot

Description

Vector and Matrix Data

example

plot3(X,Y,Z) plots coordinates in 3-D space.

  • To plot a set of coordinates connected by line segments, specify X, Y, and Z as vectors of the same length.

  • To plot multiple sets of coordinates on the same set of axes, specify at least one of X, Y, or Z as a matrix and the others as vectors.

example

plot3(X,Y,Z,LineSpec) creates the plot using the specified line style, marker, and color.

example

plot3(X1,Y1,Z1,...,Xn,Yn,Zn) plots multiple sets of coordinates on the same set of axes. Use this syntax as an alternative to specifying multiple sets as matrices.

example

plot3(X1,Y1,Z1,LineSpec1,...,Xn,Yn,Zn,LineSpecn) assigns specific line styles, markers, and colors to each XYZ triplet. You can specify LineSpec for some triplets and omit it for others. For example, plot3(X1,Y1,Z1,'o',X2,Y2,Z2) specifies markers for the first triplet but not for the second triplet.

Table Data

example

plot3(tbl,xvar,yvar,zvar) plots the variables xvar, yvar, and zvar from the table tbl. To plot one data set, specify one variable each for xvar, yvar, and zvar. 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 R2022a)

Additional Options

example

plot3(ax,___) displays the plot in the target axes. Specify the axes as the first argument in any of the previous syntaxes.

example

plot3(___,Name,Value) specifies Line properties using one or more name-value pair arguments. Specify the properties after all other input arguments. For a list of properties, see Line Properties.

example

p = plot3(___) 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.

A convenient way to plot data from a table is to pass the table to the plot3 function and specify the variables to plot.

Create vectors x, y, and t, and put the vectors in a table. Then display the first three rows of the table.

t = (0:pi/20:10*pi)';
x = sin(t);
y = cos(t);
tbl = table(x,y,t);
head(tbl,3)
ans=3×3 table
       x          y          t   
    _______    _______    _______

          0          1          0

    0.30902    0.95106    0.31416

Plot the x, y, and t table variables. Return the Line object as p. Notice that the axis labels match the variable names.

p = plot3(tbl,"x","y","t");

Starting in R2019b, you can display a tiling of plots using the tiledlayout and nexttile functions. Call the tiledlayout function to create a 1-by-2 tiled chart layout. Call the nexttile function to create the axes objects ax1 and ax2. Create separate line plots in the axes by specifying the axes object as the first argument to plot3.

tiledlayout(1,2)

% Left plot
ax1 = nexttile;
t = 0:pi/20:10*pi;
xt1 = sin(t);
yt1 = cos(t);
plot3(ax1,xt1,yt1,t)
title(ax1,'Helix With 5 Turns')

% Right plot
ax2 = nexttile;
t = 0:pi/20:10*pi;
xt2 = sin(2*t);
yt2 = cos(2*t);
plot3(ax2,xt2,yt2,t)
title(ax2,'Helix With 10 Turns')

Figure contains 2 axes objects. Axes object 1 with title Helix With 5 Turns contains an object of type line. Axes object 2 with title Helix With 10 Turns contains an object of type line.

Create x and y as vectors of random values between 0 and 1. Create z as a vector of random duration values.

x = rand(1,10);
y = rand(1,10);
z = duration(rand(10,1),randi(60,10,1),randi(60,10,1));

Plot x, y, and z, and specify the format for the z-axis as minutes and seconds. Then add axis labels, and turn on the grid to make it easier to visualize the points within the plot box.

plot3(x,y,z,'o','DurationTickFormat','mm:ss')
xlabel('X')
ylabel('Y')
zlabel('Duration')

Create vectors xt, yt, and zt. Plot the values, specifying a solid line with circular markers using the LineSpec argument. Specify the MarkerIndices property to place one marker at the 200th data point.

t = 0:pi/500:pi;
xt(1,:) = sin(t).*cos(10*t);
yt(1,:) = sin(t).*sin(10*t);
zt = cos(t);

Source table containing the data to plot, specified as a table or a timetable.

Table variables containing the x-coordinates, specified using one of the indexing schemes from the table.

Indexing SchemeExamples

Variable names:

  • A string, character vector, or cell array.

  • A pattern object.

  • "A" or 'A' — A variable called A

  • ["A","B"] or {'A','B'} — Two variables called A and B

  • "Var"+digitsPattern(1) — Variables named "Var" followed by a single digit

Variable index:

  • An index number that refers to the location of a variable in the table.

  • A vector of numbers.

  • A logical vector. Typically, this vector is the same length as the number of variables, but you can omit trailing 0 or false values.

  • 3 — The third variable from the table

  • [2 3] — The second and third variables from the table

  • [false false true] — The third variable

Variable type:

  • A vartype subscript that selects variables of a specified type.

  • vartype("categorical") — All the variables containing categorical values

The table variables you specify can contain numeric, categorical, datetime, or duration values. If you specify multiple variables for more than one argument, the number of variables must be the same for each of those arguments.

Example: plot3(tbl,["x1","x2"],"y","z") specifies the table variables named x1 and x2 for the x-coordinates.

Example: plot3(tbl,2,"y","z") specifies the second variable for the x-coordinates.

Example: plot3(tbl,vartype("numeric"),"y","z") specifies all numeric variables for the x-coordinates.

Example: plot3(tbl,"x","y",["z1","z2"]) specifies the table variables named z1 and z2 for the z-coordinates.

Example: plot3(tbl,"x","y",2) specifies the second variable for the z-coordinates.

Example: plot3(tbl,"x","y",vartype("numeric")) specifies all numeric variables for the z-coordinates.

Target axes, specified as an Axes object. If you do not specify the axes and if the current axes is Cartesian, then plot3 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: plot3([1 2],[3 4],[5 6],'Color','red') specifies a red line for the plot.

Note

The properties listed here are only a subset. For a complete list, see Line Properties.

Color, specified as an RGB triplet, a hexadecimal color code, a color name, or a short name. The color you specify sets the line color. It also sets the marker edge color when the MarkerEdgeColor property is set to 'auto'.

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 from 0 to F. 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.

Line width, specified as a positive value in points, where 1 point = 1/72 of an inch. If the line has markers, then the line width also affects the marker edges.

The line width cannot be thinner than the width of a pixel. If you set the line width to a value that is less than the width of a pixel on your system, the line displays as one pixel wide.

Marker size, specified as a positive value in points, where 1 point = 1/72 of an inch.

Marker outline color, specified as 'auto', an RGB triplet, a hexadecimal color code, a color name, or a short name. The default value of 'auto' uses the same color as the Color 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 character vector or a string scalar that starts with a hash symbol (#) followed by three or six hexadecimal digits, which can range from 0 to F. The values are not case sensitive. Thus, the color codes '#FF8800', '#ff8800', '#F80', and '#f80' are equivalent.

Marker fill color, specified as 'auto', an RGB triplet, a hexadecimal color code, a color name, or a short name. The 'auto' option uses the same color as the Color property of the parent axes. If you specify 'auto' and the axes plot box is invisible, the marker fill color is the color of the figure.

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 from 0 to F. 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.

Tips

  • Use NaN or Inf to create breaks in the lines. For example, this code plots a line with a break between z=2 and z=4.

     plot3([1 2 3 4 5],[1 2 3 4 5],[1 2 NaN 4 5])

  • plot3 uses colors and line styles based on the ColorOrder and LineStyleOrder properties of the axes. plot3 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 or LineStyleOrder properties on the axes. You can also call the colororder function to change the color order for all the axes in the figure. (since R2019b)
