如何在圖表外添加有關圖表的其他詳細信息

Question

我是JFreeChart的新手。我用JFreeChart創建了折線圖。現在，我想添加有關圖表外側的附加細節（即在圖表的左側和底部）。另外，我想用生成的圖表保存所有的信息。任何機構都可以幫助我。

Answer 1

對於軸，更好地利用循環使代碼更清潔：

for(double i=0;i<3.70;i+=0.1){ series.add(i,0.0) } 
for(  i=0;i<1.2;i+=0.1){ series2.add(0.0,i) } 

我personnaly使用JavaFX的，而不是舊版本揮杆Jelement，所以你可以使用一個BorderPane（https://docs.oracle.com/javase/8/javafx/api/javafx/scene/layout/BorderPane.html你這裏的圖片），所以你可以把一些元素周圍（並把borderpane在一個區，現場建設者的可能性較大（http://code.makery.ch/library/javafx-8-tutorial/fr/part1/）

編輯：https://code.lds.org/nexus/content/sites/maven-sites/stack/modules/swing/1.1.1/apidocs/org/lds/stack/swing/BorderPane.html這裏是你的揮杆版本，與setNorthComponent /南/ ...方法的JPanel;）

EDIT2：

這裏，要小心有好名字對於你的班級「啓動器」，如果它不行，那麼你可以添加控制器的按鈕
