java - Jfreechart 将文本/注释/标签放置在图表轮廓上的所需位置和线条上

标签 java text charts position jfreechart

我正在尝试重新创建一个类似于下图中的图表:

desired chart

目前，我设法得到了这个:

work in progress chart

如何添加缺少的元素，例如 setLabelLocation() 方法允许的边界之外的轴标签。另外如何在显示的位置上添加值标签？

对于最后一条绿色垂直线，该线似乎被虚线轮廓覆盖，这里我尝试在图表的右侧绘制辅助轴，但该线仍在背景中，有任何想法可以解决这个问题？

这是尝试的代码:

最佳答案

正如所讨论的here ，获得所需轴标记的一种方法是添加 SymbolAxis右侧，如图here及以下。此外，

  • 轴/图重叠可能反射(reflect)了 setAxisOffset() 中 RectangleInsets 的使用，下面省略；相反，会显示第三个域标记。

  • 刻度线位置支持由 DataAxis 提供和DateTickMarkPosition。

  • 不要用空格填充标题，而是使用 setPadding()，参见 here及以下。

  • 调整图表的整体大小，如图 here .

  • 在 Swing 上下文中，仅在 event dispatch thread 上构建和操作 GUI 对象。 。
