Reply To: Collection data with Ajax

[Vishwas R]

Michael,

You can parse the JSON data and pass dataPoints to respective dataSeries in chart options as shown below

$.ajax({
  type: 'GET',
  url: 'https://api.npoint.io/191c62a905159a49256e',
  dataType: 'json',
  success: function(field) {
    for (var i = 0; i < field.length; i++) {
      dataPointsA.push({
        x: field[i].time,
        y: field[i].xxx
      });
      dataPointsB.push({
        x: field[i].time,
        y: field[i].yyy
      });
    }

    var chart = new CanvasJS.Chart("chartContainer", {
      title: {
        text: "JSON from External File"
      },
      exportEnabled: true,
      data: [{
        type: "line",
        name: "line1",
        xValueType: "dateTime",
        dataPoints: dataPointsA
      }, {
        type: "line",
        name: "line2",
        xValueType: "dateTime",
        dataPoints: dataPointsB
      }, ]
    });

    chart.render();

  }
});

Here is an example for loading JSON data from external source using AJAX.

You can also refer loading data from external JSON in this example.
