It might be desirable to have the same Y-axis when plotting identical metrics in one cross plot.

for instance, comparing SAR-device.sda.await.

Do you envision comparing GC.GCPause with SAR-device.sda.await in same Y-axis?

[zhenyun]

no. Only comparing: (1) the same sub-metric (e.g., cpu.util) from different hosts; (2) same sub-metric from different devices (e.g. sda.await sdb,await); Ideally, we should allow the user to control whether to use same y-scale or not.
