How to add lines to scatter/bubble chart?

Question

Hi,
I have bubble and scatter charts for which I'd like to add some horizontal lines, such as sales goals. Anyone?
Appreciate any suggestions/ideas.

Answer 1

FileWriter(String fileName, boolean append) throws IOException
If append is true, then output is appended to the end of the file. Here is an example:
import java.io.*;
public class  AATest1
     public static void main(String args[])
          try
               //Open file for writing:
               File data = new File("C:\\TestData\\javaIO.txt");
               BufferedWriter out = new BufferedWriter(
                              new FileWriter(data) );
               out.write("hello");
               out.close(); //flushes buffer
               //Open file for appending:
               out = new BufferedWriter(
                    new FileWriter(data, true) );
               out.write(" world");
               out.close(); //flushes buffer
          catch(IOException exc)
               System.out.println("io error writing to file");
}
