Plot discrete sequence data

Syntax

Description

A two-dimensional stem plot displays data as lines extending from the x-axis. A circle (the default) or other marker whose y-position represents the data value terminates each stem.

stem(Y) plots the data sequence Y as stems that extend from equally spaced and automatically generated values along the x-axis. When Y is a matrix, stem plots all elements in a row against the same x value.

stem(X,Y) plots X versus the columns of Y. X and Y are vectors or matrices of the same size. Additionally, X can be a row or a column vector and Y a matrix with length(X) rows.

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

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

h = stem(...) returns handles to Line graphics objects.

Examples

Create a stem plot of 10 random numbers:
