The metrics page for a web service displays 3 graphs: Memory, CPU, and Bandwidth.

Additionally, when a user places the cursor over a specific spike, a line indicating the exact timeframe is synchronized across all 3 charts making it easy to identify trends relating to one or the other.

While CPU/Memory trends are aligned (Memory 4:41PM = CPU 4:41PM), the Bandwidth line also appears but for a different timeframe (in this case 11AM).

This creates some confusion since the line is placed on both graphs, but is unrelated to one another.

Memory/CPU graphs are useful when synchronized, but could bandwidth have its own line that is not synchronized to the other two graphs?
