帮我写AS读取传感器数据后用jfreechart库画图的Java代码

好的，以下是示例代码：

import java.awt.BorderLayout;
import java.awt.Color;
import javax.swing.JFrame;
import javax.swing.JPanel;
import org.jfree.chart.ChartFactory;
import org.jfree.chart.ChartPanel;
import org.jfree.chart.JFreeChart;
import org.jfree.chart.plot.PlotOrientation;
import org.jfree.data.category.DefaultCategoryDataset;
import org.jfree.ui.ApplicationFrame;

public class SensorDataChart extends ApplicationFrame {

   private static final long serialVersionUID = 1L;

   public SensorDataChart(String applicationTitle, String chartTitle) {
      super(applicationTitle);
      JFreeChart lineChart = ChartFactory.createLineChart(
         chartTitle,
         "Sensor Reading",
         "Value",
         createDataset(),
         PlotOrientation.VERTICAL,
         true,true,false);
         
      ChartPanel chartPanel = new ChartPanel(lineChart);
      chartPanel.setPreferredSize(new java.awt.Dimension(560 , 367));
      chartPanel.setBackground(Color.WHITE);
      setContentPane(chartPanel);
   }

   private DefaultCategoryDataset createDataset() {
      DefaultCategoryDataset dataset = new DefaultCategoryDataset();
      // Add sensor readings here
      dataset.addValue(1.0, "Sensor 1", "Reading 1");
      dataset.addValue(1.2, "Sensor 1", "Reading 2");
      dataset.addValue(1.5, "Sensor 1", "Reading 3");
      dataset.addValue(1.8, "Sensor 1", "Reading 4");
      dataset.addValue(2.1, "Sensor 1", "Reading 5");
      dataset.addValue(2.5, "Sensor 1", "Reading 6");
      return dataset;
   }

   public static void main(String[] args) {
      SensorDataChart chart = new SensorDataChart("Sensor Data Chart", "Sensor Readings");
      chart.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
      chart.pack();
      chart.setVisible(true);
   }
}
