[Solved]-React highcharts, show legends as bar-Highcharts

You can create additional column charts and place them under the legend items:

chart: {
    events: {
        load: function() {
            var columnChart1 = Highcharts.chart("columnChart1", columnChartOptions),
                columnChart2,
                xPos = this.legend.group.translateX,
                yPos = this.legend.group.translateY,
                items = this.legend.allItems;

            columnChartOptions.series[0].data = [76];
            columnChartOptions.series[0].color = 'yellow';
            columnChart2 = Highcharts.chart("columnChart2", columnChartOptions);

            columnChart1.renderTo.style.top = yPos + 50 + 15 + items[0]._legendItemPos[1] + 'px';
            columnChart1.renderTo.style.left = xPos + 'px';

            columnChart2.renderTo.style.top = yPos + 50 + 15 + items[1]._legendItemPos[1] + 'px';
            columnChart2.renderTo.style.left = xPos + 'px';
        }
    }
}
