Actually, the "timeofday" data type does support formatting, both on h- and
vAxes. This might only be available (especially for vAxis) in the next
release, now 1.1, but you should be able to specify, e.g. vAxis: { format:
"HH:mm:ss" } to get the default format, and you can show milliseconds with
"HH:mm:ss.SSS". Negative time and times greater than 24 hours should also
work.
