hi
looks like this would be the RMS value of the signal; so you simply have to calculate that rms value and plot it with the same length as your x vector

No it is not the RMS it is just a value. And how i plot in the same figure of the wave ? Can you write the code pl?

something like
plot(xData,yData,'b',xData,my_value*ones(length(xData)),'g')
