stairs

Stairstep graph

Syntax

stairs(Y)

stairs(X,Y)

stairs(___,LineSpec)

stairs(___,Name,Value)

stairs(ax,___)

h = stairs(___)

[xb,yb] = stairs(___)

Description

stairs(Y) draws a stairstep graph of the elements in Y.

• If Y is a vector, then stairs draws one line.

• If Y is a matrix, then stairs draws one line per matrix column.

stairs(X,Y) plots the elements in Y at the locations specified by X. The inputs X and Y must be vectors or matrices of the same size. Additionally, X can be a row or column vector and Y must be a matrix with length(X) rows.

stairs(___,LineSpec) specifies a line style, marker symbol, and color. For example, ':*r' specifies a dotted red line with asterisk markers. Use this option with any of the input argument combinations in the previous syntaxes.

stairs(___,Name,Value) modifies the stairstep chart using one or more name-value pair arguments. For example,'Marker','o','MarkerSize',8 specifies 8 point circle markers.
