根据点数，您可以动态调整图表的高度。例如：

const pointWidth = 20;
let allowChartRedraw = true;

Highcharts.chart('container', {
  chart: {
    events: {
      render: function() {
        if (allowChartRedraw) {
          const pointsAmount = this.series[0].points.length;
          allowChartRedraw = false;
          this.setSize(
            null,
            pointsAmount * pointWidth * 2 + (this.chartHeight - this.plotHeight),
            false
          );
          allowChartRedraw = true;
        }
      }
    }
  },
  series: [{
    type: 'bar',
    pointPadding: 0,
    groupPadding: 0,
    pointWidth,
    data: [...]
  }]
});
