If not, how should I modify? Thank you!

But I have no idea what type/properties of polarplot are saved in fig file. F1 doesn't tell me the answer.

They are regular cartesian plots which have two axes that have hidden handles, and they have a bunch of text labels to mark the radii and the angles, and they have a patch to define the circle background. The handle that is returned by polar() is the handle of the main plot; I've forgotten at this time of night whether it is the main axis or the main lineseries (lineseries I _think_), either way it is a matter of a few second to find the XData and Ydata. However, the XData and YData will be in cartesian coordinates. I seem to recall that newer versions push everything down a level into a hggroup, which lends more flexibility in moving the whole ensemble and in adding datatips that are polar based. Anyhow, if you look at some of my old postings, keyword polar, then I describe the layering in some of them, at least as it existed at that time.
