**Stairstep Plots**

Stairstep plots display data as the leading edges of a constant interval (i.e., zero-order hold state). This type of plot holds the data at a constant *y*-value for all values between *x(i)* and *x(i+1)*, where *i* is the index into the *x* data. This type of plot is useful for drawing time-history plots of digitally sampled data systems.

**Example - Stairstep Plot of a Function**

For example, define a function `f`

that varies over time,

Use `stairs`

to display the function as a stairstep plot and a linearly interpolated function.

Annotate the graph and set the axes limits.

label = 'Stairstep plot of e^{-(\alpha*t)} sin\beta*t'; text(0.5,-0.2,label,'FontSize',14) xlabel('t = 0:10','FontSize',14) axis([0 10 -1.2 1.2])
