Line or bar over the y-axis variable in x-y plot

(1.) Hi everyone, I want to put bar/line over the y –axis variable (Load Capacity ‘W’ ) because that variable is non-dimensional like (W ̅ ). So it will looking like W ̅ . I am using following plot command-

       ep1 =[0.0  0.10  0.20  0.30  0.40];  
       W  =[0.0  0.12  0.24  0.36  0.48];
       h = plot(ep1,W,'--r')
       set(h(1),'linewidth',2.5);
       xlabel('Eccen.Ratio, \epsilon','Fontsize',10) 
       ylabel('Load Capacity, W','Fontsize',10)

How to write the plot command in above MATLAB Prog. for putting the bar above or over the y- axis variable? Kindly help me in this regard. Thanks, SANDEEP SONI, Surat, India; E-mail ID - [e-mail]

To put a bar over your variable, you have to specify the interpeter as 'latex' and then use the appropriate LaTeX commands in the string in your ylabel call.

It’s not easy to see, but it’s there:

ep1 =[0.0  0.10  0.20  0.30  0.40];
W  =[0.0  0.12  0.24  0.36  0.48];
h = plot(ep1,W,'--r');
set(h(1),'linewidth',2.5);
xlabel('Eccen.Ratio, \epsilon','Fontsize',10)
ylabel('Load Capacity, $\bar{W}$','Fontsize',10, 'Interpreter','latex')
