Format label chartjs

Hey guys.

I’m using chart.js and trying to format the y-axis label from 25000 to 25.000 $.
I’ve read several pages about either set the default to this: = function(label){
    return label.value.toString().replace(/\B(?=(\d{3})+(?!\d))/g, ".");

or set the options:

var options = {
        animation: false,
        function(label){return  ' $' + label.value.toString().replace(/\B(?=(\d{3})+(?!\d))/g, ",");}

or scope the options on html with options=“options”. But nothing works. Some of my code looks line thise, where i define the data and type of the chart.

var loadCharts = function(){
                    var ctx = document.getElementById("lineChart");
                    var myChart = new Chart(ctx, {
                      type: 'line',
                      data: data
