這個按照你使用的.Net版本有所區別，不過簡單的來說，可以分為使用一張表生成圖表（DataBindTable）、使用X值和Y值的集合來生成圖表（DataBindXY）、使用指定的Y值集合來生成圖表（DataBindY）這幾種大的方式，根據所提供參數的不同還可以分為幾個小類，具體的你可以看一下DataPointCollection下面的成員，希望對你有幫助，如有疑問請追問或是Hi
dotNetCharting的展示效果由於是將生成的一張臨時圖片展現在頁面所以比較絢，說到這dotNetCharting在使用的時候需要建一個臨時文件夾用於存放臨時生成的圖片文件，不要擔心臨時文件會越來越多，頁面在每次加載的時候會刪除掉以前的圖片文件，這樣的方式也為我將圖片插入到Excel中提供了幫助，頁面和統計圖生成以後在導出Excel的時候可以利用腳本在頁面獲取圖片在服務器上的地址，得到這一地址就可以在生成Excel的時候，將數據和圖片一起插入。
