使用JFreeChart在XY空间中绘制轨迹 [英] Plotting a locus in XY space using JFreeChart

问题描述

我想在二维空间中绘制粒子的轨迹.

I would like to plot the locus of a particle in two dimensional space.

我的数据是X，Y坐标的序列，我想绘制它们.

My data is a sequence of X,Y coordinates and I would like to plot these.

将感谢所有指向示例的指针，这些示例演示了如何执行此操作.

Would appreciate any pointers to examples that show how to do this.

下面是一个轨迹图示例:

An example of a locus plot can be seen below:

注意:我想将路径显示为带箭头的连续线，箭头指示运动方向.

Note: I'd like to show the path as a continuous line with arrows showing the direction of motion.

谢谢.

推荐答案

ChartFactory.createScatterPlot()，如图所示

ChartFactory.createScatterPlot(), illustrated here, might be a good starting point.

FastScatterPlot，在此处引用，并在附录:查看您的修订问题，我还没有看到这样的渲染器.您可能会看 org.jfree.chart.annotations (例如，使用GeneralPath的XYShapeAnnotation).这些 ArcTest 变体可以提供指导.另请参见 PointyThing .

Addendum: Looking at your revised question, I've not seen a renderer like that. You might look at a org.jfree.chart.annotations such as XYShapeAnnotation using a GeneralPath. These ArcTest variations may offer guidance. See also PointyThing.
