我們可以通過GroupedStackedBarChart繪製折線圖

我正在嘗試創建一個GroupedStackBar圖表，其中顯示了每個客戶在過去三個月對每種產品的收入，並添加了描繪與客戶在每個時間段內完成的會議的折線圖。我正在使用JasperReports創建一個PDF報告，使用通常的圖表定製工具來準備它。我們可以通過GroupedStackedBarChart繪製折線圖

下面的快照猜測我試圖創建圖表：

chart image 。

該報告需要描繪每個客戶的月收入和會議。正如，表明Client1收入提供了X Mn和曾在十一月M會議，Y百萬的收入和12月N會議等..

所以，我的X軸有兩個集團 - 客戶和月（s）在最後一個季度。此外，收入還與產品進行了堆疊。因此，我有點合併了兩個不同的數據集 - 每個客戶的收入度量，幾個月，每個客戶的產品與會議的度量值，月份來構建圖表。

，我會用於產生圖表創建的示例程序：

上述程序的輸出不顯示圖表作爲是必需的。相反，線圖表顯示JAN13與Client1與Client2與Client2P會議，Q與Client2會議，JAN13，R與Client3會議，JAN13和X會議Feb13，爲Y會議Feb13等等。也就是說，對於客戶端的分組是不被尊重的。我嘗試改變折線圖數據集中的row-key/column-key而沒有收益率。

請您指點一下，以正確獲取折線圖？

謝謝。

我無法上傳一個簡單的jpg顯示圖表 - 我正在開發的圖表，因爲我沒有10個信譽點:( – saiyyer 2013-02-22 13:33:32

你可以用Ireport創建一個多軸圖表，我有這個類似的要求 – Sharad 2013-02-23 03:36:35

我首先想到的是要實現自定義渲染器 - 出GroupStackedBarRenderer和LineAndShapeRenderer的混合物 - 但下面的僞分組是比較容易;）

所以我把它換成了GroupedStackedBarRenderer用StackeBarRenderer並插入一個虛擬列之間的組。客戶的分組類別標籤由第二個域軸完成 - 幸運的是，無論使用多少個客戶端/組，第二個類別軸的標籤都集中在第一個軸的組中...

嗯，我們重新審視了我們的報告設計並調整了一下以適應Jasper的報告。但@kiwiwings，你的黑客完美的作品。非常感謝您的解決方案。 – saiyyer 2013-04-25 17:21:12
