Hi, boys, I want to show the time evolved with drawing the different pictures, but the former time is still left. I want to know if the forrmer time can be cleared.

int numFrames = 19;  // The number of frames in the animation
int frame = 0;
PImage[] images = new PImage[numFrames];
PFont plotFont;   
void setup()
{
  size(417, 250);
  frameRate(2.5);
 
  images[0]  = loadImage("0.bmp");
  images[1]  = loadImage("1.bmp");
  images[2]  = loadImage("2.bmp");
  images[3]  = loadImage("3.bmp");
  images[4]  = loadImage("4.bmp");
  images[5]  = loadImage("5.bmp");
  images[6]  = loadImage("6.bmp");
  images[7]  = loadImage("7.bmp");
  images[8]  = loadImage("8.bmp");
  images[9]  = loadImage("9.bmp");
  images[10] = loadImage("10.bmp");
  images[11] = loadImage("11.bmp");
  images[12] = loadImage("12.bmp");
  images[13] = loadImage("13.bmp");
  images[14] = loadImage("14.bmp");
  images[15] = loadImage("15.bmp");
  images[16] = loadImage("16.bmp");
  images[17] = loadImage("17.bmp");
  images[18] = loadImage("18.bmp");

plotFont= createFont("Geogeria",20);
textFont(plotFont);
smooth();
}
 
void draw()
{
  frame = (frame+1) % numFrames;  // Use % to cycle through frames
  image(images[frame], 0, 0);
  fill(0);
  textSize(20);
  String title= nf(frame,2)+":00";    --------   Here!
  text(title, 10,240);
 
  String label= "Unique interaction";
  text(label, 210,240);
 
}
