Make 3 lines with different values at Y axis

Hi!

I want to ask, how to make 3 lines at y axis on the bar graph?

I have this command:

clear

y=[0.0975 0.1270 0.2785 0.6324 0.8147 0.9058 3.6330];

x=[1 2 3 4 5 6 7]; k=bar(x,y,'b'); xlabel('Sorted Contrast'); ylabel('Contrast Value');

and I want to make 3 different lines at y axis and the values are:

L1 =0.7759

L2 =0.6174

L3= 0.3897

However, I dont know how to make it. Is there any suggestions?
