How would I go about adding commas to the numbers shown in the column chart?

[Captain Gordon Freeman]

Like the title says I have a column chart that shows the values of each column on the column itself. I would like to add commas to it if possible. I have looked at this page here: https://developers.google.com/chart/interactive/docs/reference?hl=de-DE#numberformatter but I think I'm missing something because it doesn't quite work. Here's my code so far:

var chart = new google.visualization.ColumnChart(document.getElementById('homescreenDetailChart'));

    var formatter = new google.visualization.NumberFormat({

        groupingSymbol: ','

    });

    chart.draw(view, options);

What'd I miss?

You have to set the format pattern and format your data:

var formatter = new google.visualization.NumberFormat({

    pattern: '#,###',

    groupingSymbol: ','

});

// format column 1 of the DataTable

formatter.format(data, 1);
