Hello All,

I have problem with matlab legend entries. Legend entries in figure 1 and figure 2 having same colour .

I have warning message of

Warning: Ignoring extra legend entries. > In legend at 294 In Error_safe_look_ahead at 289

How can I resolve that problem any tips, I include the plot code

Thanks

 h1=figure;
      plot(h1,value_safelookahead_relerrorMarkov,'-X','LineWidth',2,...
                  'MarkerEdgeColor','b',...

Hi Oleg,

Thanks for reply. I used hold on, it's showing the legend but I still have problem with marker colour MarkerEdgeColor, MarkerFaceColor,

In all the figure MarkerEdgeColor and MarkerFaceColor having same colour instead of different colour for each MarkerEdgeColor and MarkerFaceColor for each plot.

How I resolve that problem

Many Thanks
