Hi Tushar,

You are correct, any plot which includes values greater the 2*Pi
requires the use of multiple series.

Cheers

Hi Andy,

I've shied away from using a Radar plot for parametric plots because I've
always seen it as more like a Line chart turned into a circle rather than a
XY Scatter chart.

But, as you demonstrate, it does have some advantages. There's no need to
specify theta values (though, that can be a disadvantage), and the ability
to create a filled-in plot, something not (easily?) possible with a XY
chart.

The big disadvantage is that whatever one wants to do must be accomplished
in theta = 0 to 2*Pi -- though, I am hesitant to make a claim that you might
decide to prove wrong. {grin}

That precludes something like the butterfly plot given by

x=COS(t)*(EXP(COS(t))-2*COS(4*t)-SIN(t/12)^5)
y=SIN(t)*(EXP(COS(t))-2*COS(4*t)-SIN(t/12)^5)

for 0<= t <= 24*Pi
