Why is not the second tag in the legend?

Dear all,

I have been attempting to set the two legends at the boxplot, but there might be something wrong in my code since the second tag "mean" does not appear on the final plot, do you mind cheking this out?

figure
boxplot([SOC_, SOC_Max, SOC_mean], 'Labels',{'SOC','SOC(Max)','SOC(mean)'})
hold on
meanSOCs=mean([SOC_, SOC_Max, SOC_mean]);
plot(meanSOCs,'-o')
ylabel('State of charge (%)')
grid on
hold off
legend(["Data", "mean"])

Best regards

Store the line handles returned from boxplot and plot and use them to explicitly tell legend which lines to use:

SOC_ = randn(10,1);
SOC_Max = randn(10,1);
SOC_mean = randn(10,1);

figure
h_bp = boxplot([SOC_, SOC_Max, SOC_mean], 'Labels',{'SOC','SOC(Max)','SOC(mean)'});
hold on
meanSOCs=mean([SOC_, SOC_Max, SOC_mean]);
h_m = plot(meanSOCs,'-o');
ylabel('State of charge (%)')
grid on
hold off
legend([h_bp(5,1) h_m],["Data", "mean"]) % using a blue box line h_bp(5,1)
