Legend shows just 8 from 9 entries

Hello,

I want print legend:

Leg = ["Motor 1","Motor 2","Motor 3","Motor 4","Motor 1 harm","Motor 2 harm","Motor 3 harm","Motor 4 harm","Traj"];
legend([p1 p2 p3 p4 p6 p11 p12 p13 p14],Leg);

but i get just:

I tried allready to change a places and plot shows just 8 entries on the same time. What is wrong?

Thank you!

Highly probable that one of your plot handle is empty.

No, I tried allready to change a places p_x1 an p_x2 and some names. Plot have stil just 8 entries and there are nonzero!

Paste full code.

Here please, but now works! I rename also some plots.

figure('Name','Measured Data','NumberTitle','on');
        hold on
        myspec(x,Fs);
        title("Result: " + file_name,'Interpreter','none')
        hold on
        p1 = plot(t_ref,m1,'-o','LineWidth',1.5,'Color','r');
        hold on
        p2 = plot(t_ref,m1*2,'-o','LineWidth',1.5,'Color','r');
        hold on
        p3 = plot(t_ref,m2,'-o','LineWidth',1.5,'Color','g');
        hold on
        p4 = plot(t_ref,m2,'-o','LineWidth',1.5,'Color','g');
        hold on
        p5 = plot(t_ref,m3,'-o','LineWidth',1.5,'Color','b');
        hold on
        p6 = plot(t_ref,m3,'-o','LineWidth',1.5,'Color','b');
        hold on
        p7 = plot(t_ref,m4,'-o','LineWidth',1.5,'Color','m');
        hold on
        p8 = plot(t_ref,m4,'-o','LineWidth',1.5,'Color','m');
        colors = lines(length(Traj_interpl));
        for u = 1:length(Traj_interpl)  
            hold on;
            p9 = plot(Traj_interpl{u}(:,1),Traj_interpl{u}(:,2),'w--o','LineWidth',2,'MarkerFaceColor',colors(u,:));
        end
        for m_act = 2:30
            hold on
            set(gca, 'ColorOrder', [0.7 0.7 0.7])
            p10 = plot(t,v1*m_act,t,v2*m_act,t,v3*m_act,t,v4*m_act);
        end
        ylim([0 500]);
        xlabel('t_{seconds}')
        ylabel('Rotation 1/s') 
        Leg = ["Motor 1","Motor 2","Motor 3","Motor 4","Motor 1 harm","Motor 2 harm","Motor 3 harm","Motor 4 harm","Traj"];
        legend([p1 p2 p3 p4 p5 p6 p7 p8 p9],Leg);
        saveas(gcf, [name, '.png'])
        movefile([name, '.png'],FilePath)
        

The position of motors should be still changed, I have to change this, but - I think - its not a problem!
