Matlab Bar plot including Mean and Variance

I am trying to draw a boxplot where the height accords to the mean of
a vector and a horizontal line according to the mean + variance and
the mean - variance (see picture (should be overlaying a box plot)).
      --- -> mean + variance
       =A6
       =A6 -> hear should be the top of the boxplot according to
the mean
       =A6
      --- -> mean - variance


could anyone tell me how to draw this. errorbar is a good solution,
but it doesn't produce a box, just a line for the mean.


thanks!

use both bar and errorbar.

x=1:10 ;
y = 10*rand(size(x)) ;
L = rand(size(x)) ;
U = rand(size(x)) ;
bar(x,y)
hold on ;
h = errorbar(x,y,L,U) ;
delete(h(2)) ; % remove connecting line
hold off ;

Thank you very much. Worked great, except for matlab saying

??? Index exceeds matrix dimensions.

Error in =3D=3D> displayLearning at 65
    delete(h(2)) ; % remove connecting line


but I replaced

h =3D errorbar(x,y,L,U) ;
delete(h(2)) ;

with

 h =3D errorbar(x,y,L,U,'+') ;

which also made the connecting lines dissapear.

thank you very much again
