HighCharts multiple data points per category
<p>I want the multiple data points to be plotted on category. In the below example case , for "Jan" month I would like to plot multiple data points instead of one. Something like [20,28] in the same vertical line. Please see the series that I've for Tokyo and Jan month. I would like to pass an array of data points instead of single. (Example [20,28] instead of 28) </p>

<pre><code>$(function () {
    $('#container').highcharts({
        chart: {
            type: 'scatter'
        },
        title: {
            text: 'Monthly Average Temperature'
        },
        subtitle: {
            text: 'Source: WorldClimate.com'
        },

            categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
