[gradsusr] Help: Bins

[Mary Ndlovu]

 This is a repost. I posted this last week and got no help. I am really desperate. 

Hi, 
  
  I have calculated an index and would like to group my results into bins so i can plot the standard deviation bars. I have attached an example of what i am trying to reproduce, so how do i do this....i.e separate my indices into bins like DMI>1, 0< DMI<1 and DMI<1. Thanks
