I'm trying to plot a lot of sumulation results in the background of a graph as reference. Then, I try to show just the average and the theoretical results for comparison, but I don't know how to avoid the 500 vectors to show just three elements because in the legend the code corresponds just to the many vectors.
I can't change the order because the average and analytical results underlap the simulation results.
The bottom image corresponds to the correct code for the legend.
And this is the code for the graph.
plot(tau,RZcZc,'Color',[0.5 0.7 1],'LineWidth',0.5)
plot(tau,RZcZc_av,'LineWidth',3)
plot(tau,RZcZc_theory,'k','LineWidth',3)
title(['Autocorrelation ', '$R_{Z_{c}Z_{c}}$'],'interpreter','latex')
ylabel('Autocorrelation')
xlabel(['Normalized time ', '($f_d \tau$)'],'interpreter','latex')
legend('Simultion','Average','Analytical')
ax.FontName = 'Helvetica';
