I have an XY plot of positions and want the newest point to be an icon. Is this possible in JFreeChart?

推荐答案

在xy图上，您需要跟踪最后添加的xy点，然后使用以下内容添加它：

On an xy plot you would need to keep track of the last xy point added and then add it using something like the following:

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);
