我有一個overplot條形圖應用於LineChart，兩個不同的系列如何克隆X和Y軸？
barChart.getData().addAll(series1);
lineChart.getData().addAll(series2);
我的問題：是否有可能，以及如何，克隆BARCHART軸爲了感受一下線型圖相同的設置？
我想什麼有是一個完美的軸設置重疊。
感謝
編輯：在這個環節
我看到有從類繼承的克隆方法的方法java.lang.Object繼承
我如何使用這個方法？
感謝所有
EDIT2：下面是一個示例類顯示我的問題：它繪製折線圖，然後通過單擊添加按鈕意甲它增加了一個散點圖。
由於它繪出黃色點兩者軸線重疊，但是隻要移動圖表通過鼠標左鍵點擊左/右或上/道指和在圖表上任意位置拖動和軸熄滅同步。
的軸同樣的問題擴大X或Y軸

嘗試做一個雙向對所有根據的顯著特性之間的結合軸系 – 2013-02-22 12:24:02
我有一個類似的問題：我想創建一個先前NumberAxis的精確副本：我不能用一個新的實例創建和/或從以前的原始NumberAxis獲取參數。 我該如何解決這個問題？ – famedoro 2013-02-22 13:24:38
