You have to apply the format yourself and return it in the calculated
column, like this:
var view = new google.visualization.DataView(data);
view.setColumns([0, 1, 2, {
type: 'number',
label: 'Average',
calc: function (dt, row) {
var avg = (dt.getValue(row, 1) + dt.getValue(row, 2)) / 2;
return {v: avg, f: avg + ' ms'};
}
}]);
The returned object has two properties: "v" for the value and "f" for the
formatted value.
