java - 在JFreeChart中显示LineFunction2D

JFreeChart具有一个称为LineFunction2D(double YIntercept, double Slope)的类。我可以使用JFreeChart示例，但不能使用LineFunction2D。如何将折线图添加到JFreeChart对象？

LineFunction2D line = new LineFunction2D(.03125, (.125 - .03125));

//missing code goes here

JFreeChart chart = new JFreeChart(Plot plot);
ChartPanel panel = new ChartPanel(chart);

谢谢！

最佳答案

我认为您正在寻找的代码是对DatasetUtilities.sampleFunction2D的调用，它将数据集转换为可以添加到绘图中的am XYDataset

private static final double A = 5 / 16d;
private static final double B = 1 / 8d - A;
private double start = 1;
private double end = 10;
private int samples = 4;
private Comparable<String> seriesKey = "Regression";

...

        XYPlot plot = new XYPlot(this.data1, xAxis, yAxis, renderer1);
        LineFunction2D line = new LineFunction2D(A, B);
        XYDataset lineDS = DatasetUtilities.sampleFunction2D(line,start,end,samples,seriesKey );
        plot.setDataset(plot.getDatasetCount() + 1, lineDS);
