价值领域(措施)

PivotEngine 有几个字段集合作为属性公开:

  • fields:包含数据源中可用的所有字段。
  • valueFields:包含用作“度量”的字段,通常是引擎汇总的数值。
  • rowFieldscolumnFields:包含用作“维度”的字段,通常是用于将数据分组的字符串或日期。
  • filterFields:包含仅用于过滤数据的字段(它们不包含在输出摘要中)。

PivotPanel 允许您将多个字段副本拖动到 valueFields 集合中。执行此操作时,面板将创建具有自己属性的克隆。

这允许您使用不同的聚合和计算来汇总字段。例如,您可以显示带有总和的列,另一个带有平均值,运行总计或百分比。

尝试将“Amount”字段的几个副本拖到 valueFields 区域并更改它们的 aggregateshowAs 属性:
