How to prevent overlapping columns in Highcharts

Try reproducing the error here @ http://jsfiddle.net/jugal/bgNBG/

High-quality default charts flexibly reduce column widths if there are too many to avoid duplication.

, , column.pointWidth

    column: {           
        pointWidth : 10
    }

№ 1. column.pointWidth
, . : @http://jsfiddle.net/jugal/bgNBG/

№ 2. column.dataGrouping
, ( ) , /.

dataGrouping = {
    groupPixelWidth: 40, // Minimum width for each column
    units: [[            // Permissible groupings
        'day',
        [1, 2, 3,4,5,6]  // 1,2,3,4,5,6 days may be grouped into 1 column
        ]]
}
