stem3 - Plot 3-D discrete sequence data

Alternatives

To graph selected variables, use the Plot Selector in the Workspace Browser, or use the Figure Palette Plot Catalog. Manipulate graphs in plot edit mode with the Property Editor. For details, see Plotting Tools — Interactive Plotting in the MATLAB Graphics documentation and Creating Graphics from the Workspace Browser in the MATLAB Desktop Tools documentation.

Syntax

Description

Three-dimensional stem plots display lines extending from the x-y plane. A circle (the default) or other marker symbol whose z-position represents the data value terminates each stem.

stem3(Z) plots the data sequence Z as stems that extend from the x-y plane. x and y are generated automatically. When Z is a row vector, stem3 plots all elements at equally spaced x values against the same y value. When Z is a column vector, stem3 plots all elements at equally spaced y values against the same x value.

stem3(X,Y,Z) plots the data sequence Z at values specified by X and Y. X, Y, and Z must all be vectors or matrices of the same size.

stem3(...,'fill') specifies whether to color the interior of the circle at the end of the stem.

stem3(...,LineSpec) specifies the line style, marker symbol, and color for the stems. See LineSpec for more information.

stem3(...,'PropertyName',PropertyValue,...) specifies property name and property value pairs for the stemseries objects the function creates.

h = stem3(...) returns handles to stemseries graphics objects.

Examples

Create a three-dimensional stem plot to visualize a function of two variables.

figure
X = linspace(0,1,10);
Y = X./2;
Z = sin(X) + cos(Y);
stem3(X,Y,Z,'fill')
view(-25,30)
