sgrid
11-201
Limitations sgrid plots the grid over the current axis regardless of whether the axis
contains a root locus diagram or pole-zero map. Therefore, if the current axes
contains, for example, a step response, you may superimpose a meaningless
s-plane grid over the plot. In addition,
sgrid does not rescale the axis limits of
the current axis. T herefore, the s-plane grid may not appear in the plot if the
left half of the s-plane is not encompassed by the axis limits.
