Hi Kanta

There are several possibilities, below are two of them.

- Use margin without return arguments, such that it produces a Bode plot with the margins displayed, and save it in your favourite format:

margin (sys)
print -depsc2 fig.eps

- Use bode without return arguments, save the plot as EPS file and add the margins "by hand" in a vector graphics program like Inkscape [1].

bode (sys)
print -depsc2 fig.eps


Inkscape is free software:
