当我点击第一个或最后一个图例项目时，图表会重新绘制，但是当我点击中间的图例项目时它不会发生？这是一个错误或功能？我如何能够改变中间传奇项目的这种行为，他们还能够重新绘制图表？

您可以设置和更新xAxis的中断以隐藏空白区域：

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
      });
    }
  }
