dear all, I would like to decorate this polarplot with an arrow that starts at the origin and moves outwards at a certain angle (phi). it would be great if the arrow could also have tickmarks. does anyone have a solution? PolarPlot[ 1/(10*Sin[t]^4 + -1*Cos[t]^2*Sin[t]^2 + 0.1*Cos[t]^4 + 5*Cos[t]^2*Sin[t]^2), {t, 0, 2*Pi}, PlotRange -> All, PlotStyle -> {{Red, AbsoluteThickness[4]}}] thanks! L
