void serialEvent (Serial myPort) {// get the ASCII string:

String inString = myPort.readString();

if (inString != null) { // trim off any whitespace:

inString = trim(inString);// convert to an int and map to the screen height:

float inByte = float(inString);
inByte = map(inByte, 0, (1023 + xPos), 0, height);//map incomming value to height of screen

stroke((78 + xPos), 2 ,5 );// draw the line:
line((xPos + height), height, xPos, height – inByte);

// at the edge of the screen, go back to the beginning:
if (xPos >= width) {
xPos = 5;
background(217);
}
else {
// increment the horizontal position:
xPos++;
}
}
