Hello!
If one operates in cartesian coordinates and has a function, he can plot it using plot. If it is a data points one can consider using line function. Accordingly, if we operate in polar coordinates, for the function plotting we have polar_plot, but what if we have only data points and we need them to be plotted in polar axes? Like, if we have an array of $[\phi_i, r_i]$.
I didn't find anything appropriate (tried polar_line and line(polar=True)) so I wrote:
def polar_line(polar_points, **kwds):
return line([(r * cos(phi), r * sin(phi)) for r, phi in polar_points], **kwds)
I am wondering is there anything default in sage for plotting in polar axes by data points?
