Anyone have experience of creating Polar Plots?

I suppose you can transform your polar coordinates to rectangular. For example, take a function like

r = sin(3*alpha)

r being the radius (distance to the origin) and alpha the polar angle.

The scheme would be something like:

For alpha = alpha1 to alpha2 step DeltaAlpha
    r = sin(3*alpha)
    x=r*cos(alpha)
    y=r*sin(alpha)
'and here you can place the plotting part
'such as (if it's a picturebox):
    Picture1.Line -(x,y)
