Stairstep graph
stairs(y) stairs(x,y)
a matrix of doubles
a matrix of doubles
stairs(y)
plots the stairstep graph of y.
If y is a vector, the x-axis ranges from 1 to length(y).
If y is a matrix, the x-axis ranges from 1 to the number of rows in y. The number of columns in y is the number of stairstep graphs to plot.
stairs(x,y)
plots the stairstep graph of x and y.
