我有一個名爲'Brutto'和許多類別的'系列'（jfree paralance）條形圖;自2008年以來，每個月都會有一個。我已經旋轉了月份標籤UP-90，但它們全都擠在一起，很難閱讀，所以我想跳過其中的一些（例如，每隔一個或每三個一個，但它不只要它是整潔可讀的，並且對未來的添加而言最好是動態的，那就沒什麼關係了）。跳過JFree條形圖中的類別軸標籤
我使用的JFreeChart 1.0.16，我想我已經發現了答案，當我遇到雷盧卡斯來到補丁在SourceForge和對jfree論壇相關帖子：http://www.jfree.org/phpBB2/viewtopic.php?f=3&t=15345&start=15
不幸的是這個補丁/類沒有按」 t似乎與1.0.16一起工作;我已經嘗試了演示代碼以及爲我的用例調整演示，並且它不會拋出任何錯誤，但它對我的圖表也完全沒有影響。從SourceForge它看起來像修補程序是在2012年上次更新。
是否有某種方法可以跳過1.0.16或1.0.17中的類別標籤？如果沒有，是否有解決辦法或更新Ray的補丁以使用1.0.16？
我已經支付了JFree開發指南和演示源，但沒有看到任何有用的東西 - 讓我知道如果我錯過了那裏的東西。

對於代碼跟你玩可以用雷的演示代碼與數據集更類似於礦：

我不確定這是相關的，因爲我也使用補丁作者提供的演示代碼，但沒有結果，但我會看看我是否可以給你一些有用的東西 – eljaydub
也許你可以將代碼合併到你的問題中？也許只是一個簡單的版本來演示你的問題？ –
