How can I plot polarscatter with different marker types?

I would like to polarscatter a visual field, I need 2 different marker types (if stimulus is saw or not). I passed with the change of color but I would to change the marker type too.

if true
  sz = 50
for t = 1 : length(Area_triggered)
  if strcmp(Area_triggered(t),'T')
      c(1,t) = 1;
  else
      c(1,t) = 2;
  end
end
