How to avoid patch color in legend?

Sorry , i can to send only you a little piece of code..

here "

plot(Ax_Eq,XDates(xx_:end),TE_strum(xx_:end,i)','Color',"black",'LineWidth',width_arr(i));

(SECOND PLOT)

i plot with another color the the last part of equity

Problem is the legend:

Some are colored black in the legend.. Instead I only want the legend like those of the initial plot (FIRST PLOT)

("

plot(Ax_Eq,XDates,TE_strum(:,i)','DisplayName',STR_name{i},'Color',col(i,:),'LineWidth',width_arr(i));

")

for i=1:c
      if STR_type(i)==1  %%se sono aggregate
         SumCTR_color(b(i),:)= col(i,:); %%cosi nel draw del SumCTR_strum gli do il colore uguale
      end    
      %%********* FIRST PLOT ***********************
     plot(Ax_Eq,XDates,TE_strum(:,i)','DisplayName',STR_name{i},'Color',col(i,:),'LineWidth',width_arr(i));
     %%**********************************************
      text(Ax_Eq,r-2,TE_strum(end,i),strcat({' '},num2str(i)),'Color',col(i,:),'Interpreter','none');
      if app.OOScolorCheckBox.Value %%mi colora di nero da dove inizia solo l'OOS (se ci sono 4 sistemi prende l'OOS piu' recente!!)!
          oos=datetime(string({app.Sis.OOS}),'Format','dd/MM/yyyy');
           xx=cell2mat(app.Seraf_T(:,3));
          [~,xx_]=find(max(oos(xx))==XDates); %%max perche prendo l'OOS piu' recente!
           %%********* SECOND PLOT ***********************
          plot(Ax_Eq,XDates(xx_:end),TE_strum(xx_:end,i)','Color',"black",'LineWidth',width_arr(i));
          %%***************************************
      end
      %%******************************
  end    
%%*************************
nm=Convert_ArrayDouble_StringDollar_Struct(TE_strum(end,:)',0);
tm=compose("%s", Ntrad_strum');
leg=strcat(string(1:c)',{' - '},string(STR_name),"==>",nm," ",tm);

In the call to legend, you can specify which lines (or whatever) you want included.

Here it's legend_lines:

legend_lines = gobjects(1,c);
for i=1:c
    if STR_type(i)==1  %%se sono aggregate
        SumCTR_color(b(i),:)= col(i,:); %%cosi nel draw del SumCTR_strum gli do il colore uguale
    end    
    %%********* FIRST PLOT ***********************
    legend_lines(i) = plot(Ax_Eq,XDates,TE_strum(:,i)','DisplayName',STR_name{i},'Color',col(i,:),'LineWidth',width_arr(i));
    %%**********************************************
    text(Ax_Eq,r-2,TE_strum(end,i),strcat({' '},num2str(i)),'Color',col(i,:),'Interpreter','none');
    if app.OOScolorCheckBox.Value %%mi colora di nero da dove inizia solo l'OOS (se ci sono 4 sistemi prende l'OOS piu' recente!!)!
        oos=datetime(string({app.Sis.OOS}),'Format','dd/MM/yyyy');
        xx=cell2mat(app.Seraf_T(:,3));
        [~,xx_]=find(max(oos(xx))==XDates); %%max perche prendo l'OOS piu' recente!
        %%********* SECOND PLOT ***********************
        plot(Ax_Eq,XDates(xx_:end),TE_strum(xx_:end,i)','Color',"black",'LineWidth',width_arr(i));
        %%***************************************
    end
    %%******************************
end

nm=Convert_ArrayDouble_StringDollar_Struct(TE_strum(end,:)',0);
tm=compose("%s", Ntrad_strum');
leg=strcat(string(1:c)',{' - '},string(STR_name),"==>",nm," ",tm);
legend(Ax_Eq,legend_lines,leg,'Location','northwest','Interpreter','none','Box','off');
