Write legend on for loop plot

Hello Mathworks community,

I'm using the following loop to plot a graph for different scenarios:

figure
X = [1.182, 1.6, 1.7, 1.8, 1.9, 2]
NumberOfScenarios = [1, 2, 3]
Scenarios = string(NumberOfScenarios);
meanofscenarios =  [0.8753 0.8685 0.8617 0.9099 0.9062 0.902 0.9044 0.9010 0.8975 0.9067 0.9030 0.8993 0.9141 0.9108 0.9076 0.9178 0.9147 0.9117]
for p = 1:numel(NumeroBESS)
plot(X, meanofscenarios(p : numel(NumberOfScenarios) : end), 'linewidth', 2); hold on
set(gca,'linewidth',2)
title('Title','FontName', 'Cambria', 'FontSize', 13); xlabel('Ratios DC/AC', 'FontName', 'Cambria', 'FontSize', 13); ylabel('Porcentaje de almacenamiento efectivo', 'FontName', 'Cambria', 'FontSize', 13)
legend('Scenario %d ', Scenarios(p)); hold on
end

I'm getting the graph I desire but I'd like the legend to display: Scenario 1, Scenario 2 and Scenario 3, but I'm not getting the expected output. I'm attaching an image of the plot I'm getting.

Could someone please give me a hand?

Than you

Santos

hello

try this :

X = [1.182, 1.6, 1.7, 1.8, 1.9, 2]
NumberOfScenarios = [1, 2, 3]
Scenarios = string(NumberOfScenarios);
meanofscenarios =  [0.8753 0.8685 0.8617 0.9099 0.9062 0.902 0.9044 0.9010 0.8975 0.9067 0.9030 0.8993 0.9141 0.9108 0.9076 0.9178 0.9147 0.9117]

figure(1),hold on
for p = 1:numel(NumeroBESS)
    plot(X, meanofscenarios(p : numel(NumberOfScenarios) : end), 'linewidth', 2); 
    set(gca,'linewidth',2)
    title('Title','FontName', 'Cambria', 'FontSize', 13);
    xlabel('Ratios DC/AC', 'FontName', 'Cambria', 'FontSize', 13);
    ylabel('Porcentaje de almacenamiento efectivo', 'FontName', 'Cambria', 'FontSize', 13)
    legend_str{p} = (['Scenario '  num2str(Scenarios(p))]);
end

legend(legend_str);
hold off

Thank's Mathieu! Now is working fine. I was wondering if perhaps you knew a way of doing it avoiding data convertion to cell?

I'm intending to use this in Simulink and I know that it doesn't like changing the format of data.

Thank's again!

hmm , does string array better fit your needs ?

X = [1.182, 1.6, 1.7, 1.8, 1.9, 2]
NumberOfScenarios = [1, 2, 3]
Scenarios = string(NumberOfScenarios);
meanofscenarios =  [0.8753 0.8685 0.8617 0.9099 0.9062 0.902 0.9044 0.9010 0.8975 0.9067 0.9030 0.8993 0.9141 0.9108 0.9076 0.9178 0.9147 0.9117]

figure(1),hold on
for p = 1:numel(NumeroBESS)
    plot(X, meanofscenarios(p : numel(NumberOfScenarios) : end), 'linewidth', 2); 
    set(gca,'linewidth',2)
    title('Title','FontName', 'Cambria', 'FontSize', 13);
    xlabel('Ratios DC/AC', 'FontName', 'Cambria', 'FontSize', 13);
    ylabel('Porcentaje de almacenamiento efectivo', 'FontName', 'Cambria', 'FontSize', 13)
     legend_str(p,:) = strcat('Scenario : ' , Scenarios(p));

end

legend(legend_str);
hold off

Thank's Mathieu! This works better in my case. Thank's for the help!
