聚合运算

功能概述

当我们在可视化组件的绑定区域添加字段之后,可视化组件即可获取到数据集中的数据,然后开始进行显示和绘制。

但系统的可视化功能远远不止于此,它在获取到数据集中的数据后,还可以进行多种聚合运算和快速运算进而快速得到满足实际需求的新指标。

其中:

对数值类型的字段支持的计算方式包括: 聚合运算合计、平均数、最大值、最小值计数与计数(不重复))和 快速运算排名运算、占比运算、累计运算、移动运算、以及与时间相关的同环比运算 等)。

对非数值类型的字段支持的计算方式包括: 计数和计数(不重复) 。经过计数运算后的非数值类型字段,也可以进行快速运算。

聚合运算

当数值绑定区中绑定字段时,均默认进行聚合运算。

绑定度量字段时,提供七种聚合运算方法:包括 合计、平均数、最大值、最小值、计数、计数(不重复) 等。默认的聚合运算是合计,用户可根据需要进行修改。
