It's because at longer history the values are averaged over longer time intervals. Steve
It would seem that is what is happening, but is that appropriate for things like CPU values? 100% of the CPU is constant over time. And it looks like when he takes a certain path to zoom in, he sees expected values.

- In the 48-hour graph, I see 2 spikes for "user" this morning that were near 60%.
- In the 12-day graph, those same 2 spikes only go up to about 30%.
- In the 48-day graph, the spikes only go up to about 15%.
- In the 576-day graph, the values hover around 10%.
