title: Connecting points with lines to create a line graph
body: <p>Hello I am fairly new to java and have been stuck on this problem for awhile so hopefully someone will be able to save me. Basically I am creating a program that can graph an equation and right now I'm testing out x^2 between -10 and 10. I can get the points to graph in the right spots but I can't figure out how to fill in the spots in between the points so it looks like a real graph.</p>
  
  <p>Here's my code:</p>
  
  <pre><code>import java.util.Scanner;
  import javax.swing.JFrame;
  import java.awt.*;
  
  class PlotGraph extends JFrame{
  
  
  public void paint(Graphics l){
  
      l.drawLine(50, 300, 550, 300); //x axis
      l.drawLine(300, 550, 300, 50); //y axis
      //Orignin x = 300 y = 300
  
      int xmin, xmax, y, tmin, tmax;
      xmin =(-10);
      xmax = 10;
      int x_bet, y_bet;
  
      while(xmin&lt;=xmax){
          y = 300-(xmin*xmin);
          l.drawLine(xmin+300, y, xmin+300, y);
  
          //while(x_bet&gt;xmin){
          //l.drawLine(, , , );
          //}
  
          xmin++;
      }
  
  
  
  }
  
  public static void main(String [] args) {
  
      PlotGraph graph = new PlotGraph();
      graph.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
      graph.setSize(600, 600);
      graph.setVisible(true); 
      graph.setTitle("PlotGraph");
  
  }
  
  
  }
  </code></pre>
