How to plot the data with the mean plus standard deviation ?

How to plot the data with the mean plus standard deviation ? Generate a graph (X verse Y1, Y2). Y1 is the mean plus standard deviation, Y2 is the average less standard deviation. However I would like the graph area between Y1 and Y2 stay filled. My data are similar to these:

    X              Y1               Y2
1.054171  82.09164  71.74552  
1.154169  85.30468  82.58082  
1.254169  78.50763  75.39015  
1.356947  84.39281  63.49761  
1.445835  85.00555  62.59616  
1.545835  86.27113  64.9023  
1.645836  91.08072  87.28493  
1.745834  89.34505  87.97645  
1.845835  89.40639  80.56947  
1.945835  85.54469  78.97661  
2.045835  83.65078  79.415

fill([x;flipud(x)],[y1;flipud(y2)],'k')

Another one of those cases that is so obvious you'd think area would have the option or there would be another builtin function to do it, but no...

File Exchange is your friend, however; always do a search there first...
