Plot with mean and std of variables

I have a basic plot as follows. How can I display mean and std of X, Y, and Z in the legend?

    Plot1=plot(T,X)
    hold on
    Plot2=plot(T,Y)
    hold on
    Plot3=plot(T,Z)
    legend([Plot1, Plot2, Plot3], 'X','Y','Z')

Just use sprintf and the mean and std functions:

Plot1=plot(T,X);
hold on
Plot2=plot(T,Y);
Plot3=plot(T,Z);
legend([Plot1, Plot2, Plot3],...
    sprintf('X (mean=%.1f,std=%.1f)',mean(X,'omitnan'),std(X,'omitnan')),...
    sprintf('Y (mean=%.1f,std=%.1f)',mean(Y,'omitnan'),std(Y,'omitnan')),...
    sprintf('Z (mean=%.1f,std=%.1f)',mean(Z,'omitnan'),std(Z,'omitnan')))

What to do if Y contains NaN?

That's a problem of your data, not the code to put the results in the legend. Try using nanmean and nanstd or use the 'omitnan' flag.
