導出爲excel並顯示圖表

我正在開發此應用程序，需要我提供一個選項以導出爲excel並根據用戶選擇在excel中生成圖形。現在，我已經使用了JExcel和JFreechart的組合來生成excel工作表和顯示圖形。我無法做的是爲特定列生成圖形，因爲我需要提供單元格範圍。導出爲excel並顯示圖表

因此，有沒有其他的方法可以做到這一點？我需要編寫通用代碼來顯示數據和圖形，以便它適用於所有類型的數據。

圖表也可以在Excel中完成。 – 2013-03-08 05:48:18

當excel文件被創建時，它也必須有圖形。我無法打開文件，然後創建圖形 – 2013-03-08 05:55:48

*「..根據用戶選擇在excel中生成圖形。」*如果我是具有選擇的用戶，則選擇Open Office over Excel。 – 2013-03-08 06:16:54
