stem
Plot discrete sequence dataA two-dimensional stem plot displays data as lines extending from the x-axis. A circle (the default) or other marker symbol whose y-position represents the data value, terminates each stem.stem(Y)stem(X,Y)stem(...,'fill')stem(...,LineSpec)h = 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.
h = stem(...)
returns handles to Line graphics objects.
