obtain "gca" and "gcf" from an existing fig file, which was generated by "plotyy"

I plan to modify the exiting fig and therefore, the "gca" and "gcf" information is needed. but get(gca) is only valid for the first layer of the plot. But I also want modify the second layer.
so how can I get information for both layers, i.e., gca1 and gca2?
Thanks

FigureNumber = openfig('TheName.fig');
axes_handles = findobj(FigureNumber, 'type', 'axes');

openfig() will create a figure. Figures are never nested. The created figure will be at exactly the same layer as it was when it was created. The only difference may be in the figure number.

The doc (R2012a) says:
[AX,H1,H2] = plotyy(...) returns the handles of the two axes created
in AX and the handles of the graphics objects from each plot in H1 and
H2. AX(1) is the left axes and AX(2) is the right axes.
