Reading a CSV or JSON Formatted DATA FILE into the HTML5-based Chart instead of Embedding it into the CODE?

[Lee Deneault]

Dear Google Groups,

Instead of EMBEDDING the following DATA, seen below, into HTML5 Code...

    function drawChart() {
        var data = google.visualization.arrayToDataTable([
          ['Year', 'Sales', 'Expenses'],
          ['2004',  1000,      400],
          ['2005',  1170,      460],
          ['2006',  660,       1120],
          ['2007',  1030,      540]
        ]);

I would like to be able to actually READ this very same data from either a CSV or a JSON formatted DATA FILE!

Needless to say, any insight would be GREATLY appreciated!

Thanks, in advance, for your time and consideration!

Best Regards,

LEE

Hello Lee,

Maybe something like this -

$(document).ready(function () {

        $.ajax({

           url: "/Reporting/LeaveList",

           data: "",

           dataType: "json",

           type: "POST",

           contentType: "application/json; chartset=utf-8",

           success: function (data) {

               chartData = data;

           },

           error: function () {

               alert("Error loading data! Please try again.");

           }

       }).done(function () {

           // after complete loading data

           google.setOnLoadCallback(drawChart);

            drawChart();

        });

   });
