目前我正在硬编码系列的值，如下所示

   // Create a new series using the previously created axis for X axis
     let chartSeries = this.chart.addPointSeries({ pointShape: PointShape.Circle, xAxis: createdAxis })
        .setName(' operation')
        .setPointFillStyle(seriesColor)
        .setPointSize(5)

但我想从数据中获取系列名称
