Another way to 'determine' what the minimum value will end up as is to tell
the chart to use the value that you want. For bar and column charts, the
default minimum value (and the baseline) really should be 0, and that will
likely happen in a future version of the charts. But for now, you can
force that to happen by adding a minValue option, like so:
vAxis: {title: "Cups", minValue: 0}
Not exactly a direct answer to your question, but maybe it will help.
