Can anyone recommend a method of setting the X axis to be a constant width across multiple instances of a bar chart?

See this jsFiddle: <http://jsfiddle.net/LCYwW/1/>

The first chart is an example of placing the data for 2 locations in a single chart. In this case, Highcharts automatically adjusts the X axis width to accommodate both location labels. 

However, I need to separate these 2 locations into separate charts, but maintain the same proportions of X Axis to bar area width for both charts. See charts 2 and 3 in the example. In this case, Highcharts picks an X axis width that suits just the single location and the 2 charts do not line up when stacked.

Is there a method to get the individual charts to maintain the same proportions as each other? I tried setting the xAxis.labels.style.width attribute, and it does *something*, but doesn't seem to be a concrete width. See <http://jsfiddle.net/LCYwW/3/>

This example is easiest to see in the jsFiddle, but SO is requiring me to post the code:

```
 $('#containerAll').highcharts({
    chart:{
        type: 'bar'
    },
    series: [
        {
        name: 'Male',
        data: [{"name":"58.1%","y":0.581}, {"name":"18.1%","y":0.181}]
    },
        {
            name: 'Female',
            data: [{"name":"58.5%","y":0.585}, {"name":"28.5%","y":0.285}]   
        }
    ],
    xAxis: {
        categories: ['Short Name', 'Much Longer Location Name']   
    }
});

$('#container1').highcharts({
    chart:{
        type: 'bar'
    },
    series: [
        {
        name: 'Male',
        data: [{"name":"58.1%","y":0.581}]
    },
        {
            name: 'Female',
            data: [{"name":"58.5%","y":0.585}]   
        }
    ],
    xAxis: {
        categories: ['Short Name'],
        labels: {
            style: {
                width: 200
            }
        }
    }
});

 $('#container2').highcharts({
    chart:{
        type: 'bar'
    },
    series: [
        {
        name: 'Male',
        data: [{"name":"18.1%","y":0.181}]
    },
        {
            name: 'Female',
            data: [{"name":"28.5%","y":0.285}]   
        }
    ],
    xAxis: {
        categories: ['Much Longer Location Name'],
        labels: {
            style: {
                width: 200
            }
        }
    }
});

```
