Local phat json file

[Riccardo Sordo]

Hi!

i can't pass a json file i stored on the pc disk as an argument for the graph, any ideas?  

  var jsonurl = "./jsondata.txt";  

*************************code function***************************************************

$(document).ready(function(){

  // Our ajax data renderer which here retrieves a text file.

  // it could contact any source and pull data, however.

  // The options argument isn't used in this renderer.

  var ajaxDataRenderer = function(url, plot, options) {

    var ret = null;

    $.ajax({

      // have to use synchronous here, else the function

      // will return before the data is fetched

      async: false,

      url: url,

      dataType:"json",

      success: function(data) {

        ret = data;

      }

    });

    return ret;

  };

 

  // The url for our json data

  var jsonurl = "./jsondata.txt";

 

  // passing in the url string as the jqPlot data argument is a handy

  // shortcut for our renderer.  You could also have used the

  // "dataRendererOptions" option to pass in the url.

  var plot2 = $.jqplot('chart2', jsonurl,{

    title: "AJAX JSON Data Renderer",

    dataRenderer: ajaxDataRenderer,

    dataRendererOptions: {

      unusedOptionalUrl: jsonurl

    }

  });

});
