I have some code for the following plot: however, when I try to introduce the legend for some reason it gives properties A and B for a square in both cases even though the plots includes points which are circles and others which are squares.

figure
% plot(Rv, ur(Rm,Knm))
 hold on
  plot(0.0014,403.07,'bs')
