Use the errorbar function on the line of your choice. The easiest way to do this is to plot that line, then use hold to plot the others:
figure(1)
errorbar(Traffic, EngsetPb, barvector)
hold on
plot( ... the rest ... )
hold off
grid
Hypothetical variables here.

Awesome, Great. Done Cheers. This is what i get. Still some work left in it as the red graph should match the green graph for me.

Do you have the Statistics Toolbox?
x = 1:10;
y = sin(x);
e = std(y)*ones(size(x));
plot(x,y,'b')
hold on
errorbar(x,y,e,'bo','markerfacecolor',[0 0 1])
Not sure exactly what you mean by "between red and green graphs"
I'm assuming that each data point is an estimate and you have an associated confidence inteval that you want to represent

Thank you for the reply. The red graph is my calculated blocking probability and i want to show the errorbar on this graph. What is mean by confidence interval? Sorry, if it is a very basic question as i am not as good when it comes to statistic.

Presumably this probability comes with some associated error, you just want to use that error in errorbar()
