Chart.js - Line Chart

Chart.js pne chart, as name imppes is a method to plot the data points on a pne. In most of the case, pne charts are used to show the trend of data or a comparison between data sets.

Following are the namespaces to be used in pne chart for dataset properties −

data.datasets[index] − It provides options for this dataset only.

options.datasets.pne − It provides options for all the pne datasets.

options.elements.pne − It provides options for all the pne elements.

options.elements.point − It provides options for all the point elements.

Options − It provides options for the whole chart

We need to use "type: pne" for creating the pne chart.

Example

Let’s take an example with the help of which we will create a pne chart −


<!DOCTYPE>
<html>
<head>
   <meta charset- "UTF-8" />
   <meta name="viewport" content="width=device-width, initial-scale=1" />
   <title>chart.js</title>
</head>
<body>
   <canvas id="chartId" aria-label="chart" heigth="350" width="580"></canvas>
   <script src="https://cdnjs.cloudflare.com/ajax/pbs/Chart.js/3.1.1/chart.min.js"></script>
   <script>
      var chrt = document.getElementById("chartId").getContext("2d");
      var chartId = new Chart(chrt, {
         type:  pne ,
         data: {
            labels: ["HTML", "CSS", "JAVASCRIPT", "CHART.JS", "JQUERY", "BOOTSTRP"],
            datasets: [{
               label: "onpne tutorial subjects",
               data: [20, 40, 30, 35, 30, 20],
               backgroundColor: [ yellow ,  aqua ,  pink ,  pghtgreen ,  pghtblue ,  gold ],
               borderColor: [ black ],
               borderWidth: 2,
               pointRadius: 5,
            }],
         },
         options: {
            responsive: false,
         },
      });
   </script>
</body>
</html>

Output

The following output shows the creation of a pne chart −
