在開發系統的時候有許多數據分析需要用圖形的方式來表現出，這樣更直觀又清淅。如果我們使用高級去動態
生成統計圖表的話不但編寫起來非常困難，而且實用性不是很好，從美觀的角度上講也是很設計的。然而Microsoft公司提供了一個專們的矢量畫圖語言，這就是VML.
如果要用VML去畫靜態頁面的話那是比較好看也好操作，但實用性不是很高。但要是畫出來的圖所表示的數據
是從數據庫里面讀取下來的可以動態表示要統計的內容的話，那實用性就不言而喻了。
最近我們也要做一個數據統計圖表，我想如果能把VML畫圖做成一個控件那該多很，做自定義控件（本人才疏學淺）我不怎么會做，但我們公司有個.NET很牛 的人，我經常看到他重寫.net里自帶的控件使這些控件變得更好用,于是我也產生一種想法,看能不能把VML也嵌套進去.結果做的還是有點起色.下面跟大 家分享一下.

我是把VML圖表用Lable控件顯示出來的,給Lable類添加了一些自定義屬性.（在下面的代碼里面有的屬性還沒有用到用與以后擴展）
