修改视图显示

功能概述

数据模型设计器的画布中以圆圈代表数据表也称作“ 节点 ”,圆圈之间的箭头代表数据过滤的方向,在每个圆圈周围会显示表的基数。

我们知道基数表示在数据过滤时哪个表是“ 1 ” 方,哪个表是“ N ”方。这个很重要,因为数据过滤时,总是“ 1 ” 方的表过滤“ N ”方的表。

也就是说,在仪表板中我们将“ 1 ”的一方作为分类或系列,将“ N ”的一方作为数值。有关表关系的更多介绍,请见表关系说明

修改节点和基数显示

选择菜单中的模型设置 >视图设置,右侧弹出视图设置的设置项目,可以设置节点名称和基数隐藏与否。

隐藏节点名称后当通过滚轮缩小画布视图时,节点名称将不显示。

隐藏基数时,将不显示圆圈周围的基数。

左图为显示基数效果,右图为隐藏基数后效果。

(当视图缩小到一定程度后,即使开启了显示基数,基数也会隐藏)
