How do I disable auto scaling on the Traffic Graph?

[toysareforboys]

I run the traffic graph 24/7 on a monitor and it would be a lot easier to see big traffic spikes if the traffic graph didn't auto scale. I would like to lock it at 50/10 so the minor traffic doesn't show up as big spikes and attract my attention unnecessarily.

If anyone knows what to hack in status_graph.php or if there's another way please let me know.

Thanks!
