use json url data in a bar graph

Question

This is the json data stored in a URL(example : http://localhost/icx/test/link.html). this data is live and it changes with time

    [{
        "call_time": "0",
        "total_inc_traffic": "1363.10",
        "total_out_traffic": "88.70"
    }, {
        "call_time": "1",
        "total_inc_traffic": "479.57",
        "total_out_traffic": "36.98"
    }, {
        "call_time": "2",
        "total_inc_traffic": "239.57",

        "total_out_traffic": "328.28"
    }]

The bar-graph javascript code is given below. The above url data is needed to be used in this graph

    <script>
    var options = {
      chart: {
        height: 255,
        type: "bar"
      },

        bar: {
          horizontal: false,
          columnWidth: "55%",
          endingShape: "rounded"
        }
      },

        enabled: false
      },
      stroke: {

How can I use this URL (example : http://localhost/icx/test/link.html) in my javascript bar graph code? Please help if anyone have any idea

Answer 1

When you say "json data stored in a URL" do you mean like this?

http://localhost/icx/test/link.html?data=example_data

This is called GET data. If you are storing all that given data in the URL that is a bit of a bad idea since URLs do have a limit to their length (usually 2048 characters).

As for displaying the bar chart, a plugin like canvasJS would help you out nicely, there is a code example right on the front page.

Answer 2

You should use AJAX and jQuery to get data from Link like below:

$(document).ready(function () {
var output=[];
  $.ajax('path of your link', 
  {
    dataType: 'json', // type of response data
    timeout: 500,     // timeout milliseconds
    success: function (data,status,xhr) {   // success callback function
        console.log(data);
        output=data;
        /** Here you have to separate data received from link into 3 different array variables which then you can use in chart code where right now you have static array. **/
    },
    error: function (jqXhr, textStatus, errorMessage) { // error callback 
        console.log('Error: ' + errorMessage);
    }
  });
});
