[Octave-bug-tracker] [bug #39495] polar plot should have a circular rho/theta axis

[Stefan Mahr]

Follow-up Comment #14, bug #39495 (project octave):

I removed 'lim = 1.1 * rtick(end);' because this leads to problems with 'hold
on' plot: The axis get larger and larger with every plot.


polar(1:6,ones(1,6))
hold on
polar(1:6,ones(1,6))
polar(1:6,ones(1,6))


A solution could be to replace the 'oldxlim' stuff with following lines:


    if (! isprop (hax, "rtick"))
      addproperty ("rtick", hax, "data");
    endif
    
    oldrtick = max (get (hax,'rtick'));
    if (! isempty (oldrtick))
      maxr = max (maxr, oldrtick);
    endif
