LCD: erasing printed data? clearing specific fields?

Other Hardware Displays

here is an example of what i am doing, with a commented out portion where i was trying to print blanks where otherwise there would be leftover numbers.

  int calibration[4];

int X1 = ircam.Blob1.X;
  int Y1 = ircam.Blob1.Y;
  if (result & BLOB1)
  {
    lcd.setCursor(9,0); 
    lcd.print("X: ");     
    lcd.setCursor(0,1);       
    lcd.print("Left: "); 
    lcd.setCursor(9,1); 
    lcd.print("Y: ");   
    lcd.setCursor(11,0);
//    lcd.rightToLeft();
//    if(X1 < 1000){lcd.print(" ");}
//    if(X1 <  100){lcd.print("  ");}
//    if(X1 <  10){lcd.print("  ");}
    lcd.print(X1); 
//    lcd.leftToRight();
    lcd.setCursor(11,1);
    lcd.print(Y1);
