Highcharts悬停xAxis标签的独特价值

Question

高等问题的新手。

有一个函数可以解析散点图的xAxis标签。工作正常，但值太长并被截断。这些需要在悬停时显示，而xAxis标签上显示的值应该是括号中包含的字符串中的最后一个单词。示例和代码如下。有时间试图找到有关在Highchart中更改xAxis的悬停结果的任何信息。

原始字符串：root.D_seasonality.D_poly [poly0]

在parseLabels函数之后。可见图表标签：“poly0”。

预期悬停：“seasonality_trend_poly0”（当前图表标签）。

尝试将函数格式化或插入到HighchartOptions / xAxis中，但没有运气。

打字稿：

    parseLabels(uniqueFeatures) {
    this.labels = [];
    for (let i = 0; i < uniqueFeatures.length; i++) {

      let trimmedFeature = '';

      let curFeature = uniqueFeatures[i];
      let start = curFeature.search('>') + 4;
      curFeature = curFeature.substr(start, curFeature.length);

      let end = curFeature.search('<');
      if (end === -1) {
        end = curFeature.search('\[');
      }

      let key = curFeature.substr(0, end);

      trimmedFeature = trimmedFeature + key;
      curFeature = curFeature.substr(end + 1, curFeature.length);

      start = 0;
      end = curFeature.search('>');

      if (end === -1) {
        if (trimmedFeature.length > 1) {
          this.labels.push(trimmedFeature);
        }
      } else {

        key = curFeature.substr(start, end);

        trimmedFeature = trimmedFeature + '_' + key;
        curFeature = curFeature.substr(end + 1, curFeature.length);

        start = curFeature.search('\[') + 1;

        if (start !== -1) {

        } else {
          if (trimmedFeature.length > 4) {
            this.labels.push(trimmedFeature);
          }
        }

        end = curFeature.search('\]');
        key = curFeature.substr(start, (end - start));

        trimmedFeature = trimmedFeature + '_' + key;

        if (trimmedFeature.length > 4) {
          this.labels.push(trimmedFeature);
        }

      }
    }
  }
