Description

Vector and Matrix Data

stem3(Z) plots entries in Z as stems extending from the xy-plane and terminating with circles at the entry values. The stem locations in the xy-plane are automatically generated.

example

stem3(X,Y,Z) plots entries in Z as stems extending from the xy-plane where X and Y specify the stem locations in the xy-plane. The inputs X, Y, and Z must be vectors or matrices of the same size.

example

stem3(___,"filled") fills the circles. Use this option with any of the input argument combinations in the previous syntaxes.

example

stem3(___,LineSpec) specifies the line style, marker symbol, and color.

example

Table Data

stem3(tbl,xvar,yvar,zvar) plots the variables xvar, yvar, and zvar from the table tbl. Specify one table variable for each dimension. (since R2022b)

example

Additional Options

stem3(___,Name,Value) modifies the stem chart using one or more name-value pair arguments.

example

stem3(ax,___) plots into the axes specified by ax instead of into the current axes (gca). The option, ax, can precede any of the input argument combinations in the previous syntaxes.

example

h = stem3(___) returns the Stem object h.

A convenient way to plot data from a table is to pass the table to the stem3 function and specify the variables to plot.

Read weather.csv as a timetable tbl. Then display the first three rows of the table.

tbl = readtimetable("weather.csv");
head(tbl,3)

Stem Plot in Specific Axes

Open Live Script

You can display a tiling of plots using the tiledlayout and nexttile functions. Call the tiledlayout function to create a 2-by-1 tiled chart layout. Call the nexttile function to create the axes objects ax1 and ax2. Create separate stem plots in the axes by specifying the axes object as the first argument to stem3.

X = linspace(-2,2,50);
Y = X.^3;
Z = exp(X);
tiledlayout(2,1)

% Top plot
ax1 = nexttile;
stem(ax1,X,Z)

% Bottom plot
ax2 = nexttile;  
stem3(ax2,X,Y,Z)

If Z is a row vector, stem3 plots all elements against the same y value at equally spaced x values.
If Z is a column vector, stem3 plots all elements against the same x value at equally spaced y values.
If Z is a matrix, stem3 plots each row of Z against the same y value at equally spaced x values.

`X` — Locations to plot values of `Z`
vector or matrix

Locations to plot values of Z, specified as a vector or a matrix. Inputs X, Y and Z must be vectors or matrices of the same size.

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 from 0 to F. 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.

`MarkerSize` — Marker size
`6` (default) | positive value

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

`MarkerEdgeColor` — Marker outline color
`"auto"` (default) | RGB triplet | hexadecimal color code | `"r"` | `"g"` | `"b"` | ...

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 string scalar or character vector 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. 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) | `"auto"` | RGB triplet | hexadecimal color code | `"r"` | `"g"` | `"b"` | ...

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 string scalar or character vector 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. Therefore, the color codes "#FF8800", "#ff8800", "#F80", and "#f80" are equivalent.

R2022b: Expanded data type support

The x, y, and z input arguments can be any numeric, logical, datetime, duration, or categorical values. In previous releases, only numeric and logical values were supported.

R2022b: Pass tables directly to `stem3`

Create plots by passing a table to the stem3 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.
