You can add an "annotation" column to your data. You can use a DataView to
calculate this automatically for you:
var view = new google.visualization.DataView(dataTable);
view.setColumns([0, 1, 2, 3, {
type: 'string',
role: 'annotation',
sourceColumn: 2,
calc: function (dt, row) {
return (dt.getValue(row, 2) * 100).toFixed(1) + '%';
}
}]);
var chart = new
google.visualization.ColumnChart(document.getElementById('coverage'));
chart.draw(view, options);
Incidentally, you could take the same approach with the tooltip column as
well, since all of the values in that are based on data that exists
elsewhere in the DataTable.
