有没有办法在点击图例项目隐藏一列后填充空间？

});

Here is live example .

当我点击第一个或最后一个图例项时，图表正在重绘，但当我点击中间的图例项时没有发生这种情况？这是错误还是功能？我如何才能将中间图例项目的这种行为更改为它们也能够引发重绘图表的事件？

提前致谢

您可以设置和更新 xAxis 的中断以隐藏空白空间:

http://jsfiddle.net/a4vcye4p/1/

  events: {
    legendItemClick: function() {
      var series = this,
        seriesIndex = series._i,
        xAxis = series.xAxis,
        newBreaks = [];
      if (series.visible) {
        newBreaks = xAxis.options.breaks;
        newBreaks.push({
          from: seriesIndex,
          to: seriesIndex + 1,
          seriesIndex: seriesIndex
        });
      } else {
        Highcharts.each(xAxis.options.breaks, function(br) {
          if (br.seriesIndex !== seriesIndex) {
            newBreaks.push(br);
          }
        });
      }
      xAxis.update({
        breaks: newBreaks
      });
    }
  }
