PolarPlot goes upto 1.2 on axis, not 1?

Hi guys,
I am trying to polarplot a function like Sin[2 x]^2, from -Pi/2 to Pi/
2, with polar ticks and gridlines enabled.

Every time I do this, the vertical axis goes up to 1.2, not 1 --- is
there any way to have this only go upto 1? (The function I'm plotting
goes upto 1 only.)

Cheers!

PolarPlot[Sin[2 x]^2, {x, 0, 2 \[Pi]}, PolarTicks -> Automatic,
GridLines -> Automatic, PlotRange -> 1]

Cheers -- Sjoerd

Sorry about that,

This is the code:

PolarPlot[Sin[2 \[Theta]]^2, {\[Theta], -\[Pi]/2, \[Pi]/2},
PolarGridLines -> True, PolarAxes -> True,
PolarTicks -> {Table[i \[Degree], {i, -90, 90, 15}], Automatic},
PlotRange -> {{0, 2}, {-1, 1}}, PerformanceGoal -> "Speed",
PlotRangeClipping -> False,
PlotStyle -> {{Red, Thick, Dotted}, {Red, Thick}},
PlotLabel -> "label"]

The 'y' axis goes to 1.2; I'd like it to go to 1, and thus have the
plot peak at the outer bold line.

Thanks.

Thanks,

PolarAxesOrigin->{90deg,1} is great and exactly what I wanted. I will
file that support request.

Copy as Input Text and paste the explicit code into your posting. Otherwise
you are asking responders to guess what you did.
