Does not quite work as expected for me.  I do get two windows in AquaTerm
but they are *not*correctly labeled i.e. they both have the same title,
namely "Figure 0". The third command does add the plot to the plot of the
first command but one has to look at the plot to be able to tell because the
plots are not labeled.

This produced a window labeled "Figure 1"  with the sinusoid plotted,
whereas you say it produced a title saying "Figure 2" which I do not
understand.

This produced a window labeled "Figure 10" as I expect.
