Question: Suboptions

Here's another really basic question.  Its about using suboptions.  The MAPLE help file gives the following info:

legendstyle=s

Legend style for a plot. The value s is a list consisting of one or more suboptions. The suboptions available for the legendstyle option include font=f and location=loc. For information on how to specify the font, see the entry for the font option. The location=loc suboption allows values top, bottom, right and left for loc.

I don't really know how to use this info.

Can someone out there give me an example of a MAPLESOFT command which creats a plot variable G of, say, sin(x) , x = 0..2*Pi , such that when G is displayed  a legend appears wihch says "Sine of x" in Times 12 point?

Thanks
