[Solved]-Reduce gap between series data in Bar Highchart-Highcharts

The options you want to play with are pointPadding (padding between bars) and groupPadding (padding between seies).

e.g.

 plotOptions: {
        series: {
            pointPadding: 0,
            groupPadding: 0.1,
        }
    },
