Developer features allow extending and enhancing Chart.js in many different ways.

1. Required Vendor files

<script src="chart.min.js"></script>

2. Binding to existing DOM element

<div id="chart-chartjs"></div>

3. Basic usage may look something like this

// Initialization
var ctx = $("#chart-chartjs");

// Chart options
var chartOptions = {
    ...
};
// Chart Data
var chartData = {
    ...
};
// Configuration
var config = {
    type: 'line',
    // Chart Options
    options : chartOptions,
    data : chartData
};
// Create the chart
var lineChart = new Chart(ctx, config);
