It's been a while since you've posted so I hope you've found your answer by now but I wanted to give you a response anyway.

You need to use the min option inside the X-Axis category. Read more about this here: http://api.highcharts.com/highcharts#xAxis

 xAxis: {
     min: 1,
     categories: ['0', '1', '2', '3', '4', '5', '6', '7', '8', '9', '10', '11']
 },

These options include the '0' as a category but the chart is drawn starting at the '1' position.

I put together a simple jsfiddle showing what you wanted to accomplish here: http://jsfiddle.net/L35DP/

I'll do you one better. We can simply use the xAxis label formatter as a mapping function to map our index values from 0,1,...,n to 1,2,...,n+1 by defining the formatter as:

xAxis: {
    labels: {
        formatter: function() {
            return this.value + 1;
        }
    },  
}

Indeed you could define this mapping function to be anything at all. For example:

formatter: function() {
    return this.value * this.value;
}
