树状图表

树状图将分层的树结构数据显示为一组嵌套矩形。每个组都被给予一个矩形，这些矩形随后被更小的表示子组的矩形所覆盖。尺寸和颜色被用来显示数据的不同数值维度。

何时使用它？

在处理大量具有分层结构的数据时，请使用树状图。当颜色和尺寸被相互关联时，树状图可以帮助识别难以发现的模式。

在清晰地在单个屏幕中显示大量信息方面，树状图也很有效。这样，查看者可以深入到特定类别中以考察进一步的信息。

说明

此时，树状图支持多达两个级别的分组。

示例

汽车制造商和型号

您有一个表，其中包含汽车库存。您想要直观地显示每家制造商的汽车型号数量，以获取库存概览。

为了直观地显示此数据，您使用树状图以：

首先按制造商，然后按型号对数据进行分组
将尺寸调整依据设置为车辆数

基于结果，您可以查看库存在制造商和型号之间的分布情况：

按州和城市统计的交易合计额

您有一个表，其中包含美国多个州和城市的交易。作为您的分析的一部分，您想要按照州和每个州内的城市直观地显示合计交易金额。

为了直观地显示此数据，您使用树状图以：

您首先按州，然后按城市对数据进行分组。
将尺寸调整依据设置为交易之和

基于结果，您可以查看下列组内的聚合交易金额开始呈现的模式：

按州和城市统计的交易数和合计金额

您有一个表，其中包含美国多个州和城市的交易。作为您的分析的一部分，您想要按照州和每个州内的城市直观地显示交易数和合计交易金额。

为了直观地显示此数据，您使用树状图。您首先按州，然后按城市对数据进行分组。您还使用下列附加设置：

尺寸调整依据计数
着色依据交易总和

基于结果，您可以确定交易在不同城市和州组合之间的分布情况，并且查看下列组内的聚合交易金额开始呈现的模式：
