Hello to everyone,

I'd like to produce a polar plot with thecorresponding "polar grid" in it (i.e. the lines corresponding to $\theta =$ constant, and the circles $r =$ constant appearing. Also, I would like to have something like the tick markers. I guess I could do something like this manually, but seems very unelegant... An idea?

For the gridlines, you can do:

sage: E = EuclideanSpace(2)
sage: polar.<r, theta> = E.polar_coordinates()
sage: polar.plot(E.cartesian_coordinates())

See this page for all plot options. For instance:

sage: polar.plot(E.cartesian_coordinates(), number_values={r: 9, theta: 17}, color='green')
