You can use the new ChartLayoutInterface (available on some, but not all,
charts) to get that data. Create a "ready" event handler with this code:
google.visualization.events.addListener(chart, 'ready', function () {
var cli = chart.getChartLayoutInterface();
var chartAreaBounds = cli.getBoundingBox('vAxis#0#gridline');
var top = chartAreaBounds.top;
var height = chartAreaBounds.height;
var yAxisBase = cli.getVAxisValue(top + height);
// or
var yAxisBase = cli.getVAxisValue(top + height - 0.5);
});
There is some margin of error involved, as the axis may not actualy line up
on a specific pixel, so sometimes you have to adjust, and the only good way
to know whether or not you have to adjust is by testing.
