[Octave-bug-tracker] [bug #55176] polar plot does not plot rho axis correctly for negative rho values

[anonymous]

Follow-up Comment #1, bug #55176 (project octave):

Hmm, text got lost somehow. Example is:


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.
