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.)

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
