Stairstep graphs are a valuable tool for creating time-history plots of digitally sampled data.
stairs(Y) function is used to generate such graphs by plotting the elements of the vector Y.
If Y is a matrix, it draws one line for each column, with the color of the lines determined by the ColorOrder property of the axes.
In the case of a vector Y, the x-axis scale spans from 1 to the length of Y, while for a matrix Y, the x-axis scale ranges from 1 to the number of rows in Y.
stairs(X, Y) allows you to plot the elements in Y at specific locations defined by the vector X.
It's important to note that the elements in X must be in a monotonic order to create a valid stairstep graph.
