Chart.js could be a simple, flexible and totally customizable jQuery chart plugin that helps you to draw bar, line, area, scatter, doughnut, pie, polar, radar and many more charts.

It's easy to get started with Chart.js. All that is needed is that the script enclosed in your page beside one canvas tag to render the chart.

Features:

• Chart.js can be installed via npm or bower.
• Supports bar charts, line charts, area charts, scatter charts, doughnut charts, pie charts, polar area charts, radar charts and many more.
• Works with tablet and mobile devices.

How to use it:

1. Include the Javascript Chart.min.js at the bottom of the web page.

<script src="https://cdn.jsdelivr.net/npm/chart.js@2.9.0/dist/Chart.min.js"></script>

2. Initialize the chart plugin to create a chart.

var ctx = document.getElementById('myChart').getContext('2d');
var chart = new Chart(ctx, {
  // The type of chart we want to create
  type: 'bar',
  // The data for our dataset
  data: {
      labels: ['January', 'February', 'March', 'April', 'May', 'June', 'July'],
      datasets: [{
          label: 'My First dataset',
          backgroundColor: 'rgb(255, 99, 132)',
          borderColor: 'rgb(255, 99, 132)',
          data: [0, 10, 5, 2, 20, 30, 45]
      }]
  },
  // Configuration options go here
  options: {
    responsive: true,
  }
});

3. Add canvas to the page with the specific ID myChart.

onResize	function	null	Called when a resize occurs. Gets passed two arguments: the chart instance and the new size.
