HighCharts full width issue

Question

Im trying to make my rendered chart fill 100% of the parent div with no success. Is there any way I can remove the gap on the left and right sides?

http://jsfiddle.net/sKV9d/

var chart = new Highcharts.Chart({
    chart: {
        renderTo: 'chart',
        margin: 0,
        width: 300,
        height: 200,
        defaultSeriesType: 'areaspline'
    },    

    series: [{
        data: [33,4,15,6,7,8, 73,2, 33,4,25],    

        marker: {
            enabled: false
        }
    }]
});

Answer 1

If you remove the options width: 300, height: 200 like this:

    var chart = new Highcharts.Chart({
chart: {
    renderTo: 'chart',
    margin: 0,
    defaultSeriesType: 'areaspline'
},    

...

it will fill automatically the container.
