GYR graphing

[kkhinklejr]

it would be nice to be able to set thresholds for warning/alerts so that graphs would stay green as long as thresholds were not exceeded, switch to yellow and red (with audio notification) when the threshholds were exceeded. 3com network supervisor does this, but hopefully it is not patented. the 3com interface also allows dynamically swapping the vertical scale between actual min/max values and some fixed/threshold value. thx.
