stem3 (MATLAB Functions)

Plot three-dimensional discrete sequence data

Syntax

stem3(Z)
stem3(X,Y,Z)
stem3(...,'fill')
stem3(...,LineSpec)
h = stem3(...)
hlines = stem3('v6',...)

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.

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

Backward Compatible Version

hlines = stem3('v6',...) returns the handles of line objects instead of stemseries objects for compatibility with MATLAB 6.5 and earlier.

Examples

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

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