// Load data asynchronously using jQuery. On success, add the data

jQuery.get('analytics.tsv', null, function(tsv) {
var lines = [],
listen = false,
date,
// set up the two data series
allVisits = [],
newVisitors = [];
try {
// split the data return into lines and parse them
tsv = tsv.split(/\n/g);
jQuery.each(tsv, function(i, line) {
// listen for data lines between the Graph and Table headers
if (tsv[i - 3] == '# Graph') {
listen = true;
} else if (line == '' || line.charAt(0) == '#') {
listen = false;
}
// all data lines start with a double quote
if (listen) {

date = Date.parse(line[0] +' UTC');
allVisits.push([

parseInt(line[1].replace(',', ''), 10)

options.series[0].data = allVisits;
options.series[1].data = newVisitors;
chart = new Highcharts.Chart(options);
});
});
</script>
above is an example code for jquery plugin 'highcharts', i am trying to get the data from a json file if the json string is as: { name: 'allVisits', data: [1, 0, 4] }, { name: 'newVisits', data: [5, 7, 3] }
the example file is getting the data from a 'tsv' file so i am trying to get the data from the json file instead.
