[Solved]-different pointWidths for series in column chart-Highcharts

You can set pointWidth on particular serie, not in plotOptions, like in the example:

 series: [{
        data: [49.9, 71.5, 106.4, 129.2, 144.0, 176.0, 135.6, 148.5, 216.4, 194.1, 95.6, 54.4]

    }, {
        pointWidth: 50,
        data: [83.6, 78.8, 98.5, 93.4, 106.0, 84.5, 105.0, 104.3, 91.2, 83.5, 106.6, 92.3]

    }]
