I am trying to change the appearance of the markers in a polar plot in octave.
r = rand(1,10); % the radius
t = 30*rand(1,10); % the angles
polar(t,r,'o') % the plot
It seems we can only change the shape, by replacing 'o' by 's' or whatever. However, I didn't find a way to change the size and the colors of the markers. Does anyone have an idea?
Thanks in advance. Best,
It is possible through the polar handle:
h = polar(t,r,'o')
% list all graphical properties for this object
get(h)
set(h,'marker','v', 'markerfacecolor','g', 'markersize',10)
yields
>> h = polar(t,r,'o') % the plot
h = -64.073
>> get(h)
