WPF 动态的条形图，（大神们...） 我都快急死了.下午之前必须完成呀
我初学WPF不到2个星期，今天要完成一个动态的条形图.
脑子就一片空白了， 求指教呀 大神们...
组长帮我下载了一个DevExpress WPF Demos
在上面有一个图形的源码是这样的
<Grid>

我只能弱弱的看懂一点点...需要显示的数据应该与一个自己写的Model想对应的
然后取值出来显示的， 那该怎么去做呢，model应该如何去写.又是如何将取出来的值放入代码中，如果不是在前台放入值，那么在后台又是怎样放入值呢.. 求指教呀
自己弄了半天，还是不能将数据显示.....
[解决办法]
通过服务去取得数据库中的数据，然后在页面下的CS文件中取得返回的数据
[解决办法]
用图片代替条形图的条状体。
图片的高度就是条形图的值。
位置自己在页面上放好。
