javascript - Chart.js Add Commas to Tooltip and Y-Axis

Question

I've tried some several answers here in stackoverflow but to no avail failed to make it work.. I'm really new in Chart.js so please bear with me.

this is what I have tried so far. Add Commas to ChartJS Data Points and this Chart.js number format

here's my code:

thanks in advance.

Chart.defaults.global.legend = {
 enabled: false
};

function load_yearly_sales_per_agent(param_year, transaction_url){
    $(".custom_loader").show();
    $(".custom_graph").hide();
    $.ajax({
        url:transaction_url,
        type:'post',
        data: {year : param_year},
        dataType:'json',
        success:function(result){
              // Bar chart
              var ctx = document.getElementById("mybarChart");
              var mybarChart = new Chart(ctx, {
                responsive: true,
                multiTooltipTemplate: "<%=addCommas(value)%>",
                type: 'bar',
                data: {
                  labels: ["January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"],
                  datasets: [{
                    label: 'Sales Per Month',
                    backgroundColor: "#26B99A",
                    data: result
                  }]
                },

                options: {
                  scales: {
                    yAxes: [{
                      ticks: {
                        beginAtZero: true
                      }
                    }]
                  }
                }
              });
              $(".custom_loader").hide();
              setTimeout(function(){
                $(".custom_graph").show();
              }, 200);
        }
    });
}

what I want is to add comma on tooltip and Y-axis.....

For your yAxes ticks options, this will add commas at the thousands marks:

ticks: {
    beginAtZero:true,
    userCallback: function(value, index, values) {
        value = value.toString();
        value = value.split(/(?=(?:...)*$)/);
        value = value.join(',');
        return value;
    }
}

Similar function can be added in a tooltip callback.
