Details:
bug #53999 solution claims to have fixed plotting of negative rho values
however a simple example (provided with polar.m!) shows this not to be the
case:
clf;
theta = linspace (0,2*pi,1000);
rho = sin (7*theta);
polar (theta, rho);
title ("polar() plot");
Negative values of rho appear to be plotted in the centre. In particular this
means its impossible to plot antenna patterns which typically have negative
gains (i.e. rho values) at many angles (i.e. theta values). Attempting to set
the axis does not work either. Note this does not appear to work in Matlab
either.
