Graph maximum displayed used as reference for a second serie

[sycoweb]

Hi,
is it a way, with dynamic scaled graph, to take the MAX "DISPLAYED" value of a data source (and not the MAX value of the data source), as to be the 100th base of a second data ?
Assuming the second data source Max value fixed (Ex. 4 GB)
i.e. on the same graph,
- Ethernet traffic, in b/s
- Free mem in GB
-> max displayed point of Eth traffic say 80 Mb/s
-> Free MEM say 1.6 GB

So, the higher point of Eth Traffic is classicly at 80 M on the graph, while Free MEM is pointed at 32 on the graph (that is 80 M / 4 G * 1.6 G = 32)

Thanks for helping (and sorry for my poor English)
