//可能大家会觉得这张图片难看。呵呵。因为数据不大合理，所以画出来的线也是乱七八糟的。

//关于这个画图的东西，有一个问题：字不能斜。这个我在下面也做了审明。不过我会尽快把它处理掉。

我先建了一个库项目，共有五个文件：
1，AnalyseBase.cs
2，DataSource.cs
3，Hismap.cs
4，Linmap.cs
5，Primap.cs
我为这个类库项目取名为：Report；namespace：Ｂiisomsoft.Report.

顺便转告一下大家,关于字不能斜的问题,我已经解决了.....呵呵...可以说它现在已经进入实用阶段.

///////////////////////////////////////////////////////
上次所讲的字不能倾斜的问题，我已经纠正。。可看下面的图片：

此主题相关图片如下：

下面我入上项目文件，以供大家下学试玩。。。由于工作较忙，一直都没有优化过。大家可以好好的优化一下。
