I have am gathering analog data with an Arduino Uno. Using Processing, I can only display one serial event at a time. I need it to store data continuously. How do I do that.

Here is my code:

1. import processing.serial.*;
   Serial myPort;
   String bits;
   PFont font;
   
   
   void setup() {
    size(800,200);
    myPort = new Serial(this, "COM1", 9600);
    myPort.bufferUntil('\n');
    font = loadFont("TimesNewRomanPSMT-12.vlw");
    textFont(font);
   }
   
   void draw() {
    //The serialEvent controls the display
   }
   
   void serialEvent (Serial myPort){
    bits = myPort.readStringUntil();
    if(bits != null){
      bits=trim(bits);
    }
   
    writeText("Bits: " + bits);
   }
   
   
   void writeText(String textToWrite){
    background(255);
    fill(0);
    text(textToWrite, width/20, 10);
   }
