Silverlight中的圖表控制元件visifire的使用

     Silverlight對於圖形影象處理方面，從1.0時代起就給予了很強大的支援，所以我們可以在Silverlight中實現非常棒的各種統計圖表，然而現在有了一些開源的專案，使得這項工作更加的簡單。

一、下載dll檔案，下載地址：http://download.csdn.net/source/3476757

二、解壓檔案，新建一個Silverlight專案，將其中的Silverlight Binaries下的dll檔案引用到Bin目錄下。

三、支援多種圖表型別，Column、Bar、Line、Stock、Bubble、Radar等等幾十種型別。

四、貼上程式碼，如下：
