[gradsusr] How to Plot error bars in a figure ?

[Jose Augusto Paixão Veiga]

Dear users,

I intend to plot error bars in a figure using GrAds. 

My data has just time dimension, once it represents the integration around a volume of the atmosphere. It has 360 monthly mean values (12 months x 30 years). However, I want to plot my figure with the error bars for the climatology, i . e. just 12 climatology months only.  

Some one, could tell me how to deal with it in GrAds ?

Thanks in advance.
