WDA基础九：BusinessGraphics

好像很少有人用这玩意。。。好难玩，好废。。。和ABAP的那个图一样废。。。。

很多报表都是用BO,BI什么做的，不仅废，而且很多BO顾问不懂代码，写出来的报表挫的要死。。。。

WDA的网页图形报表分析，将就着玩玩吧。

新建程序：ZWD_GRAPH  对应视图VIEW,窗口ZWD_GRAPH

一、节点和属性设置

context页签，新增节点：GRAPH

增加属性：DESCRIPTION         STRING

WERKS1                  I

WERKS2                  I

WERKS3                  I

二、页面布局

根节点ROOTUIELEMENTCONTAINER下加入ELEMENT :BusinessGraphics

右键BusinessGraphics对象，加入CATEGORY-描述字段-对应上面的DESCRIPTION属性

加入上面的三个数值，SERIES

分别将BusinessGraphics绑到GRAPH

CATEGORY绑到DESCRIPTION

WERKS1   ->WERKS1

WERKS2   ->WERKS2

WERKS3   ->WERKS3

初始化复制，或者动作更新值就OK了
