Error de sintaxis

[raposu]

Hola llevo varias semana con problemas para hacer funcionar un gráfico, problemas debidos a mi escaso conocimiento, cierto es que estoy no muy lejos de conseguirlo, así que toda la ayuda recibida será de agradecer:

Tengo este archivo data.php

que me genera estos datos

Categorias,14/10/12 19:00,14/10/12 18:00,14/10/12 17:00,14/10/12 16:00,14/10/12 15:00,14/10/12 14:00,14/10/12 13:00,14/10/12 12:00,14/10/12 11:00,14/10/12 10:00,14/10/12 09:00,14/10/12 08:00,14/10/12 07:00,14/10/12 06:00,14/10/12 05:00,14/10/12 04:00,14/10/12 03:00,14/10/12 02:00,14/10/12 01:00,14/10/12 00:00,13/10/12 23:00,13/10/12 22:00,13/10/12 21:00,13/10/12 20:00

datos que quiero implementar en este código

Código:

var chart; // global
/**
* Request data from the server, add it to the graph and set a timeout to request again
*/
function requestData() {
$.ajax({
url: 'data.php',
success: function(data) {
// Split the lines
var lines = data.split('\n');
$.each(lines, function(lineNo, line) {
var items = line.split(',');

// header line containes categories
if (lineNo === 0) {
$.each(items, function(itemNo, item) {
if (itemNo > 0) options.xAxis.categories.push(item);
});
}
// the rest of the lines contain data with their name in the first position
else {
$.each(items, function(itemNo, item) {
if (itemNo === 0) {
options.series[lineNo-1].name = item;

} else {
options.series[lineNo-1].data.push(parseFloat(item));
}
});
}
});
console.log(options);
var chart = new Highcharts.Chart(options);
});
});

seguro que tengo alguna coma mal, seguro que hay errores de sintaxis que me siento incapaz de resolver.

pues eso, cualquier idea me será de gran ayuda.

Gracias a todos.
