这是实时散点图的简化版本http://jsfiddle.net/ashwinp/z6QXW/8/

现在我在 x 轴上得到 0 1 2 等。我希望 x 轴上的用户定义名称。X 轴标签应该从 XLables 数组中提取。

我在这里添加了来自 jsfiddle 的相同代码

 var InfluenceCnt=0;
 var QResiduals=[];
 var XLables=[];
 var HottelingT2=[];
 var EllipseChartData;
 var EllipseShift;
 QResiduals.push('0.5356899');
 QResiduals.push('0.5356899');
 QResiduals.push('0.6356899');
 QResiduals.push('0.2356899');
 QResiduals.push('0.3356899');
 QResiduals.push('0.1356899');

 HottelingT2.push('0.1')
 HottelingT2.push('0.2');
 HottelingT2.push('0.3');
 HottelingT2.push('0.4');
 HottelingT2.push('0.5');
 HottelingT2.push('0.6');

XLables.push('a')
XLables.push('b');
XLables.push('c');
XLables.push('d');
XLables.push('e');
XLables.push('f');

您需要的选项是 xAxis 上的“类别”。尝试这个：

xAxis: {
      title: {
           text: 'Sample'
      },
      categories:XLables,

http://jsfiddle.net/euVvy/

要修复工具提示，您只需要参考“this.x”，它将返回类别名称：

                tooltip: {
                     formatter: function () {
                         return '<b>' + this.series.name + '</b><br/>X: ' +
                    this.x + '<br/> Y: ' +
                    Highcharts.numberFormat(this.y, 2);
                     }
                 },

您可以使用类别或标签格式化程序，它允许定义“显示的标签http://api.highcharts.com/highstock#xAxis.labels.formatter
