Primero se importan las clases necesarias

```

import org.opensourcephysics.display.DrawingFrame;

import org.opensourcephysics.display.DrawingPanel;

import org.opensourcephysics.display.PlottingPanel;

import org.opensourcephysics.display2d.ContourPlot;

```

La clase primero incluye la ceración del panel

```

DrawingPanel plottingPanel = new PlottingPanel("x", "y", "Contour Plot");

DrawingFrame frame = new DrawingFrame(plottingPanel);

```

Despeus se deben generar la matriz de datos

```

int SIZE = 100;

double[][] data = new double[SIZE][SIZE];

ContourPlot plot = new ContourPlot();

plot.setAll(data,-1.5,1.5,-1.5,1.5);

for(int i = 0;i < SIZE;i++) {

double x = plot.indexToX(i);

for(int j = 0;j < SIZE;j++){

double y = plot.indexToY(j);

data[i][j] = Math.exp(-(x*x+y*y));

}

}

plot.setAll(data);

plottingPanel.addDrawable(plot);

```

Finalmente carga al frame:

```

frame.setDefaultCloseOperation(javax.swing.JFrame.EXIT_ON_CLOSE);

frame.setVisible(true);

```

El código fuente del constructor se puede bajar de

[Contour.java](Contour.java)

Código del constructor

```

import org.opensourcephysics.display.DrawingFrame;

import org.opensourcephysics.display.DrawingPanel;

import org.opensourcephysics.display.PlottingPanel;

import org.opensourcephysics.display2d.ContourPlot;

public class Contour {

Contour(){

DrawingPanel plottingPanel = new PlottingPanel("x", "y", "Contour Plot");

DrawingFrame frame = new DrawingFrame(plottingPanel);

int SIZE = 100;

double[][] data = new double[SIZE][SIZE];

ContourPlot plot = new ContourPlot();

plot.setAll(data,-1.5,1.5,-1.5,1.5);

for(int i = 0;i < SIZE;i++) {

double x = plot.indexToX(i);

for(int j = 0;j < SIZE;j++){

double y = plot.indexToY(j);

data[i][j] = Math.exp(-(x*x+y*y));

}

}

plot.setAll(data);

plottingPanel.addDrawable(plot);

frame.setDefaultCloseOperation(javax.swing.JFrame.EXIT_ON_CLOSE);

frame.setVisible(true);

}

}
