feeding 2Dim data
代码语言：javascript复制
public double[][] pack2Dplotdata(SolutionSet set, int dim1, int dim2) throws JMException {
double[][] data = new double[2][set.size()];
for (int i = 0; i < set.size(); i ) {
data[0][i] = set.get(i).getDecisionVariables()[dim1].getValue();
data[1][i] = set.get(i).getDecisionVariables()[dim2].getValue();
}
return data;
}
use Jfreechart to return 2dim Jpanel
代码语言：javascript复制
public ChartPanel plot_2D(double[][] data, String name, String title) {
int chartwidth = subplot_width;
int chartheight = subplot_height;
DefaultXYDataset xydataset = new DefaultXYDataset();
xydataset.addSeries(title, data);//设置点的图标title一般表示这画的是决策变量还是目标函数值
JFreeChart chart = ChartFactory.createScatterPlot(name, "X", "Y", xydataset,
PlotOrientation.VERTICAL, true, true, false);//设置表头，x轴，y轴，name表示问题的类型
//以面板显示
ChartPanel chartPanel = new ChartPanel(chart);
chartPanel.setPreferredSize(new java.awt.Dimension(chartwidth, chartheight));
return chartPanel;
}
plot 2dim scatter
这个好说，可以参考一下JFreechart绘制2D散点图
代码语言：javascript复制
public void plot_DCV(SolutionSet set, String name, int dim1, int dim2) throws JMException {
double[][] data;
if (set.get(0).getSkillFactor() == 0) {
data = pack2Dplotdata(set, dim1, dim2);
ChartPanel chartPanel = plot_2D(data, name, "dcv");
jp3.removeAll();
jp3.add(chartPanel);
jp3.repaint();
jp3.revalidate();
jp3.updateUI();
contentPaneX.repaint();
contentPaneX.revalidate();
}
if (set.get(1).getSkillFactor() == 1) {
data = pack2Dplotdata(set, dim1, dim2);
ChartPanel chartPanel = plot_2D(data, name, "dcv");
jp4.removeAll();
jp4.add(chartPanel);
jp4.repaint();
jp4.revalidate();
jp4.updateUI();
contentPaneX.repaint();
contentPaneX.revalidate();
}
}
plot 3dim scatter
这个需要使用到matplotlib for java , 具体怎么使用可以参考使用Matplotlib 3D for JAVA画三维点阵图
代码语言：javascript复制
if (set.get(0).getSkillFactor() == 0) {
jp1.removeAll();
JPanel mgrpanel = mgr.getPanel();
mgrpanel.setPreferredSize(new Dimension(subplot_width, subplot_height));
jp1.add(mgrpanel);
} else {
jp2.removeAll();
JPanel mgrpanel = mgr.getPanel();
mgrpanel.setPreferredSize(new Dimension(subplot_width, subplot_height));
jp2.add(mgrpanel);
}
mgr.setDataInputType(MatPlot3DMgr.DATA_TYPE_FUNCTION3D);
mgr.setDataInputType(MatPlot3DMgr.DATA_TYPE_DOTS);
mgr.getProcessor().setCoordinateSysShowType(mgr.getProcessor().COORDINATE_SYS_ALWAYS_FURTHER);
mgr.getProcessor().setCoordinateSysTransformationType(mgr.getProcessor().COORDINATE_RANGE_AUTO_FIT);
Point3D[] pointsarray = new Point3D[set.size()];
ArrayList<Point3D> aa = new ArrayList<>();
mgr.getProcessor().clear();
for (int i = 0; i < set.size(); i ) {
pointsarray[i] = new Point3D(set.get(i).getObjective(0), set.get(i).getObjective(1), set.get(i).getObjective(2));
}
for (int i = 0; i < set.size(); i ) {
aa.add(pointsarray[i]);
}
mgr.addData("Objective value", aa);
mgr.setScaleX(1);
mgr.setScaleY(1);
mgr.setScaleZ(1);
mgr.setSeeta(0.6);
mgr.setBeita(1.0);
mgr.setTitle(name);
mgr.fitScreem();
// mgr.show();//这句话是开始一个新的jframe,而不是一个jpanel
try {
mgr.updateView(15);
} catch (Exception e) {
e.printStackTrace();
}
}
Point3D[] pointsarray = new Point3D[set.size()];
ArrayList<Point3D> aa = new ArrayList<>();
mgr.getProcessor().clear();
for (int i = 0; i < set.size(); i ) {
pointsarray[i] = new Point3D(set.get(i).getObjective(0), set.get(i).getObjective(1), set.get(i).getObjective(2));
}
for (int i = 0; i < set.size(); i ) {
aa.add(pointsarray[i]);
}
