Using the Chart.js

I need to use new chart.js to render the pie charts. However, I don’t know how to use it,

these are the steps I followed:

  1. Install node.js from installer then restart
  2. in command prompt: npm install npm -g
  3. add the canvas id to the place where you want to see the chart
    <canvas id="myChart" width="400" height="400"></canvas>
  4. add the script for the chart
    1. <script>
      var ctx = document.getElementById("myChart");
      var myChart = new Chart(ctx, {


new Chart is the constructor for the chart.
