linear linear domain. Default = 1 for timeresp keyword. Default
= 0 for bode keyword.
log logarithmic domain. Default = 1 for bode keyword. De-
fault = 0 for timeresp keyword.
Default units can be supplied for the magnitude and phase plots (bode, nichols,
logmagplot and phaseplot keywords) with the following keywords.
degrees Angles are specified in degrees (default = 1)
db log magnitudes are specified in decibels (default = 0).
The following keywords behave identically to those in plot. They relate directly to the
line/marker specifications and must be associated with a particular pdm.
line (default = 1). Plot as a line type.
marker (default = 0). Plot markers.
line
style refer to plot
line
width refer to plot
marker
style refer to plot
marker
size refer to plot
Some preprocessing of the data is performed by the following keyword.
unwrap Applicable to bode, nichols and phaseplot keywords.
Phase changes of 2π are unwrapped, rather than being
graphed between −π and π. Default = 1.
Outputs: graph Resulting graphical object.
