使用此代碼我可以繪製散點圖。如何將一條線添加到散點圖? (Java,jmathplot)
import javax.swing.*;
import org.math.plot.*;
public class ScatterPlotExample {
public static void main(String[] args) {
double[] x = new double[] { 60 };
double[] y = new double[] { 50 };
// create your PlotPanel (you can use it as a JPanel)
Plot2DPanel plot = new Plot2DPanel();
// add a line plot to the PlotPanel
plot.addScatterPlot("teeeeest", x, y);
// put the PlotPanel in a JFrame, as a JPanel
JFrame frame = new JFrame("a plot panel");
frame.setSize(600, 600);
frame.setContentPane(plot);
frame.setVisible(true);
}
}
兩個問題:
我怎樣才能使軸範圍從1到100?
如何在x = 0.4和y = 0.7處繪製水平線和垂直線的散點圖?
謝謝!
