Discrete Data Graphs

MATLAB has a number of specialized functions that are appropriate for displaying discrete data. This section describes how to use stem plots and stairstep plots to display this type of data. (Bar charts, discussed earlier in this section, are also suitable for displaying discrete data.)

Discrete Data Plotting Commands

Function	Description
stem	Displays a discrete sequence of y-data as stems from x-axis
stem3	Displays a discrete sequence of z-data as stems from xy-plane
stairs	Displays a discrete sequence of y-data as steps from x-axis
