Dear Mathematica Mavens,

Three questions about the Plot function and its options.

1. The following gives no problem:

Plot[Sin[x]^2, {x,0,2Pi},
	PlotLabel->FontForm[Sin[x]^2, {"Times", 14}] ]

Change the value of the FormatType option and strange things appear
along the y-axis. (I'm using Mac OS 8.1, Mathematica 3.0.) Why?

Plot[Sin[x]^2, {x,0,2Pi},
	PlotLabel->FontForm[Sin[x]^2, {"Times", 14}],
	FormatType->TraditionalForm
]

Also, no problem if we use PlotStyle.

Plot[Sin[x]^2, {x,0,2Pi},
  PlotStyle->Text[Sin[x]^2"y=" ,{3,0.5}] ]

Again, TraditionalForm seems to affect text on the y-axis.

Plot[Sin[x]^2, {x,0,2Pi},
	PlotStyle->Text[Sin[x]^2"y=" ,{3,0.5}],
	FormatType->TraditionalForm
]

2. The second question concerns the first argument of the above Text
function, namely Sin[x]^2"y". This gives the desired output but the
syntax looks strange and I have no idea why it works. The same syntax
works when used as a first argument for FontForm.

3. TextStyle seems to control not only the size, color,etc of text
placed in the middle of a plot but also the size, color,etc of the axes
labels and the number symbols placed along the axes.

 Plot[Sin[x]^2, {x,0,2Pi},

	  PlotLabel->StyleForm[Sin[x]^2,
			FontSlant->"Plain",
			FontColor->RGBColor[0,0,1],
			FontSize->16,
			FontFamily->"Times"
		      ],


	  AxesLabel->{"x", "y"},

	  PlotStyle->{Text[Sin[x]^2 ,{3,0.5}],RGBColor[0,1,0]},

	  TextStyle->{FontSlant->"Italic",
				  FontSize->12,
				  FontWeight->"Bold",
				  FontFamily->"Machias",
				  FontColor->RGBColor[1,0,0]},

	   FormatType->TraditionalForm
 ]

Can the above be modified to obtain say, yellow axes labels and magenta
number symbols along the axes?
