For the most part, the number of bars produced by PROC GBARLINE depends upon your input data and the value of the LEVELS= option on the BAR statement of PROC GBARLINE. The following code demonstrates how to produce output from PROC GBARLINE that has 5 bars:
Reset = All
Device = WIN
Cback = Beige
I am not sure to understand your problem properly :
- does your GBARLINE proc only produce ONE and only one bar (then the previous answer should fix ; you can either use the DISCRETE option in the BAR statement to get one bar per value) ;
- or do you want two SERIES of bars on the same graph, in an overlayed kind of graph ?
