Hi,
I have below to plot in a single GUI plot, but at each run I just got single plot, while I need to plot all the three sets of data, I added hold off close the old plots on each new run, thanks
plot((zi-D/2)*100,Brate);
hold off
plot((z1-D1/2)*100,Brate1);
hold off
plot((z2-D2/2)*100,Brate2);
hold off
grid on
h=line([-D*100,D*100],[1-UniTol,1-UniTol]);hold on
set(h,'LineWidth',2)
h=line([-D*100,D*100],[1+UniTol,1+UniTol]);hold on
set(h,'LineWidth',2)

"hold off" means that it is okay for MATLAB to throw away anything already plotted. You probably want "hold on" after the first plot.

"...I need to plot all the three sets of data, I added hold off close the old plots on each new run..."
That's exactly the wrong thing...it's hold on you want to not overwrite each preceding plot with the next.
Reread the documentation for hold and look at example code there to get the actual effect.
hold on
plot((zi-D/2)*100,Brate);
plot((z1-D1/2)*100,Brate1);
plot((z2-D2/2)*100,Brate2);
grid on
yline(1-UniTol,'LineWidth',2)
yline(1+UniTol,'LineWidth',2)
