我有一个位置的XY图,并希望最新的点成为一个图标。在JFreeChart中是否可能实现呢?
JFreeChart XY图中的图标

最佳回答
在xy图上,您需要跟踪最后添加的xy点,然后使用以下类似的方法添加它:
double x = 150;
double y = 300;
XYPlot plot = chart.getXYPlot();
ImageIcon imageIcon = new ImageIcon("/path/to/your/icon.png");
XYAnnotation xyannotation = new XYImageAnnotation(x, y, imageIcon.getImage());
plot.addAnnotation(xyannotation);
