Maximum bar width in Highcharts column charts

Question

I\'m using Highcharts to create some vertical bars (a.k.a. \"column charts\") a lot like here: highcharts.com/demo/column-basic

Thing is, sometimes there are 30 bars in

Ultimate solution is to wrap drawPoints and overwrite shaperArgs of each point, especially x-position and width:

(function(H) { 
    var each = H.each;
    H.wrap(H.seriesTypes.column.prototype, 'drawPoints', function(proceed) {
        var series = this;
        if(series.data.length > 0 ){
            var width = series.barW > series.options.maxPointWidth ? series.options.maxPointWidth : series.barW;
            each(this.data, function(point) {
                point.shapeArgs.x += (point.shapeArgs.width - width) / 2;
                point.shapeArgs.width = width;
            });
        }
        proceed.call(this);
    })
})(Highcharts)

Use:

$('#container').highcharts({
    chart: {
      type: 'column'
    },
    series: [{
        maxPointWidth: 50,
        data: [ ... ]
    }]
});
