Customizing the Plot Display
You can plo t da ta g e nerated by several response a na ly sis functions app lied to
one or several LTI models, as well as your own data. There are several ways
you ca n customize how you display plots:
• Store the time or frequency response data in MATLAB arrays by invoking
response analysis functions s uch as
step,andbode with output arguments
[y,t] = step(sys)
[mag,phase,w] = bode(sys)
[re,im,w] = nyquist(sys)
and use the plot command to display the result.
• Use t he
subplot and hold commands to plot several sets of data in a single
figure window.
• Use t he plot configuration menu in the LTI Viewer for time a nd frequency
responses of LTI models. For more information, see “Viewer Configuration
Window” on page 6-39.
