Aggregate Graphs not using correct Maximum value

[ShawnG]

Greetings,

I am currently using Cacti 1.1.35. We recently changed the maximum values of two graphs used in a aggregate graph from 150M to 300M, but the maximum did not change on the aggregate graph. I don't see anywhere to set the maximum other than on the data source of two graphs being aggregated.

Aggregate
CDEF:cdefg='TIME,1548167721,GT,a,a,UN,0,a,IF,IF,TIME,1548167721,GT,c,c,UN,0,c,IF,IF,+,15000000,/,100,*' \
CDEF:cdefbd='TIME,1548167721,GT,b,b,UN,0,b,IF,IF,TIME,1548167721,GT,d,d,UN,0,d,IF,IF,+,15000000,/,100,*' \

Graph1
CDEF:cdefc='a,31457280,/,100,*' \
CDEF:cdefj='b,31457280,/,100,*' \

Graph2
CDEF:cdefc='a,31457280,/,100,*' \
CDEF:cdefj='b,31457280,/,100,*' \

Is there anywhere to manually set the CDEF of the aggregate graph? Looking into it, it looks like there is no .rrd file for aggregate graphs, so I'm wondering where the graph settings are stored on the server.

Any input would be greatly appreciated.

Thanks
