[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
        }]
