First of all, I apologize if my question is a slightly the same as others question. I searched for a solution and found 3 similar questions, yet none of them worked in my case, because the examples I found use Chart.js v1.
I saw a sample using a function placed in scaleLabel
to format the numbers just like this:
var options = {
animation: false,
scaleLabel: function(label){
return '$' + label.value.toString().replace(/\B(?=(\d{3})+(?!\d))/g, ",");
}
};
The above code, however, doesn't work anymore in the new Chart.js v2.
How can I format the scale numbers in Chart.js v2?
Here is my code: https://jsfiddle.net/2n7xc7j7/
When adding option configurations, you need to make sure you nest the settings in the right sections. You can format the scale numbers by adding a callback
function to the yAxes
ticks configuration section:
options = {
scales: {
yAxes: [{
ticks: {
callback: function(value) {
return value.toString().replace(/\B(?=(\d{3})+(?!\d))/g, ",");
}
}
}]
}
};

I did this:
http://profwtelles.ddns.net/grafico2.html
var canvas = document.getElementById('chart');
new Chart(canvas, {
type: 'line',
data: {
labels: ['1', '2', '3', '4', '5'],
datasets: [{
label: 'A',
yAxisID: 'A',
data: [100, 96, 84, 76, 69]
}, {
label: 'B',
yAxisID: 'B',
data: [1, 1, 1, 1, 0]
}]
},
options: {
scales: {
yAxes: [{
id: 'A',
type: 'linear',
position: 'left',
}, {
id: 'B',
type: 'linear',
position: 'right',
ticks: {
max: 1,
min: 0
}
}]
}
}
});
I hope to help you. Best Regards
In V3 the locale
property has been added. This makes it so all the numbers on the scales an tooltips get formatted correctly automatically in the numberformat of that country code:
// Element const ctx = document.getElementById("myChart") // Data const data = { labels: ['First', 'Second', 'Third', 'Fourth'], datasets: [{ label: 'Sample', data: [2982, 1039, 3200, 2300], backgroundColor: "rgba(90, 150, 220, 0.85)", borderColor: "rgba(70, 120, 180, 1)", borderWidth: 2 }], } // Options const options = { locale: 'en-US' }; const chart_trans_hari = new Chart(ctx, { type: 'bar', data: data, options: options });
<canvas id="myChart"></canvas> <script src="https://cdnjs.cloudflare.com/ajax/libs/Chart.js/3.6.0/chart.js"></script>
