You can get the range of data with getColumnRange() (
https://developers.google.com/chart/interactive/docs/reference#DataTable_getColumnRange
)
and then compute the ticks you need from that. You'll probably want to
round up the range to the nearest multiple of 1, 2, or 5 times a power of
10.
We should offer a way to specify a tick formatting function, so you could
simply use the absolute value of whatever ticks are computed based on your
data.
