[Solved]-Highchart specific width stack column bar graph-Highcharts

You should use the following options instead of pointWidth to be responsive and not fixed:

plotOptions: {
    series: {
        pointPadding: 0, // Defaults to 0.1
        groupPadding: 0.01 // Defaults to 0.2
    }
},

A working DEMO for setting width of column bars irrespective of the chart size.

You will have to use pointWidth option like:

$(function () {
    $('#container').highcharts({
        chart: {
            type: 'column'
        },
        xAxis: {
            categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
        },

        plotOptions: {
            series: {
                pointWidth: 40//width of the column bars irrespective of the chart size
            }
        },

        series: [{
            data: [29.9, 71.5, 106.4, 129.2, 144.0, 176.0, 135.6, 148.5, 216.4, 194.1, 95.6, 54.4]
        }]
    });
});

series: [{
            name: strSeriesTitle,
            data: arrData,
            pointWidth: 28
        }]
