如何使用 Amchart 做虚线阈值？

Question

这是我使用的阈值：

这是图表：

const graphHighs = {
  pk: series.pk,
  lineColor: series.seriesMetaData.colorHex,
  lineThickness: series.graph.thickness,
  valueField: `${series.pk.uuid}${series.seriesMetaData.reportType}-highs`,
  valueAxis: series.seriesMetaData.unitOfMeasurement,
  lineAlpha: series.graph.opacity,
  type: "line"
};

const graphLows = {
  pk: series.pk,
  lineColor: series.seriesMetaData.colorHex,
  valueAxis: series.seriesMetaData.unitOfMeasurement,
  lineThickness: series.graph.thickness,
  valueField: `${series.pk.uuid}${series.seriesMetaData.reportType}-lows`,
  lineAlpha: series.graph.opacity,
  type: "line"
};

我需要把线改成虚线（dashed line）谢谢这是图像的 link：2

Answer 1

需要添加破折号长度：14。

const graphHighs = {
    pk: series.pk,
    lineColor: series.seriesMetaData.colorHex,
    lineThickness: series.graph.thickness,
    valueField: `${series.pk.uuid}${series.seriesMetaData.reportType}-highs`,
    valueAxis: series.seriesMetaData.unitOfMeasurement,
    lineAlpha: series.graph.opacity,
    **dashLength: 14,**
    type: 'line',
   }
const graphLows = {
     pk: series.pk,
     lineColor: series.seriesMetaData.colorHex,
     valueAxis: series.seriesMetaData.unitOfMeasurement,
     lineThickness: series.graph.thickness,
     valueField: `${series.pk.uuid}${series.seriesMetaData.reportType}-lows`,
     lineAlpha: series.graph.opacity,
     **dashLength: 14,**
     type: "line"
    };
