[gradsusr] Help with bar plotting using GrAds

[Jose Augusto Paixão Veiga]

Dear all,

I need some help to plot a graph using the set gxout bar command. 

I want to plot one variable from three different sources, so when I use the commands bellow as part of my main script:

'set t 1 12'
'set gxout bar'
'set bargap 70'
'set barbase 0'

'set vrange -5 7'

'd var1'
'd var2'
'd var3'

I get a graph like the attached file. However, in this case the GrAds software plots every single variable in just "one" bar, i. e., for January we can see the results "superposed" to each other. But I prefer to have three bars for each month plotted instead "one" bar containing three values. So, how can I change it to get the plot I need?  

Any hint will be very welcomed.
