補充 Chart 的組成示意圖
另外，V 回復的問題，關於發布的設定，沒看到實際訊息，
猜測可能是暫存目錄的設定，這篇文章有提到。
這邊再仔細說明一下，除了上述的 config 設定外，在 server 發佈時，
由於 Chart 會產生圖表的暫存圖片，因此需要指定暫存路徑，所以
需要在 config 中設定路徑，預設的暫存目錄路徑是 c:\TempImageFiles\
圖表儲存方法(storage=file|memory|session)及目錄指定(dir|url)
<appSettings>
<!--不同儲存的格式設定與絕對路徑-->
<add key="ChartImageHandler" value="storage=file;timeout=20;dir=c:\TempImageFiles\;"/>
<add key="ChartImageHandler" value="storage=memory;timeout=20;dir=c:\TempImageFiles\;"/>
<add key="ChartImageHandler" value="storage=session;timeout=20;dir=c:\TempImageFiles\;"/>
<!--相對路徑 ~表示是在網站路徑下-->
<add key="ChartImageHandler" value="storage=file;timeout=20;url=~\;"/>
<add key="ChartImageHandler" value="storage=file;timeout=20;url=~/TempImageFiles/;"/>
</appSettings>
