The polar plot representation is the graphical representation of Y(jω).The polar plot is obtained as the locus of the real and imaginary parts of Y(jω) in the polar plane.The coordinates of the polar plot are the real and imaginary parts of Y(jω).For example, we reconsider the open-loop system for a translational mechanism (5.13), Y 1 (s) = k G /s(ms + k f). Radius values taken in the plot can be vector or matrix and the negative values are represented as zero. Angles at which to display lines extending from the origin, specified as a vector of increasing values. MATLAB labels the lines with the appropriate angle values, unless you specify different labels using the ThetaTickLabel property.
