How to add another plot on top

[zmz1988]

Hi, thanks s o much for the nice plotting tool! I really like it. I have been successfully generate my chromosome-shape ideogram. Now I would like to use the synteny function to draw a synteny plot.

I know RIdeogram can do that, but I would like to add panels such as GC content, gene density and so on on top of the synteny plot, rather than in the chromosome-shape ideogram. May I ask how I should do it? I guess the code should be more or less similar to the chromosome-shape one? Many thanks in advance!
