Highcharts multiple data points between xAxis

Question

I'm using Highcharts and am trying to get multiple points between any point on the xAxis. (Eg, I'd like 4 points between October and November.) How can I do this?

I've tried adding [] on y: to specify multiple values, but that didn't work. I just can't seem to get anything to work, and there aren't any examples of this on highcharts website that I can find.

$(function () {
    var chart;
    $(document).ready(function () {
        chart = new Highcharts.Chart({
            chart: {
                renderTo: 'container',
                type: 'area'
            },
            title: {
                text: "Title"
            },
            credits: {
                enabled: false
            },
            xAxis: {
                categories: ["October", "November", "December", "January", "February", "March"],
                tickmarkPlacement: 'on',
                title: {

You need to specify the x axis values

data: [{
                y: 3,
                x: Date.UTC(2012, 9, 9)
                date: 'October 9th, 2012',
                unlocked: 1,
                potential: 1,
            }, {

You also need to drop the xaxis categories, and make the xa is type 'datetime' An example is here http://www.highcharts.com/demo/spline-irregular-time
