Hello, im using proccessing for graphs, but i want a linear graph, what function do i need to use to make a normal line like in this graph:

Im new to proccesing, ive tried to change and add some code but i get error all the time.

here is the code!

// Graphing sketch
 // This program takes ASCII-encoded strings
 // from the serial port at 9600 baud and graphs them. It expects values in the
 // range 0 to 1023, followed by a newline, or newline and carriage return
 // Created 20 Apr 2005
 // Updated 18 Jan 2008
 // by Tom Igoe
 // This example code is in the public domain.
 import processing.serial.*;
 Serial myPort;        // The serial port
 int xPos = 1;         // horizontal position of the graph
 void setup () {
 // set the window size:
 size(400, 300);        
 // List all the available serial ports
 // I know that the first port in the serial list on my mac
 // is always my  Arduino, so I open Serial.list()[0].
 // Open whatever port is the one you're using.
 myPort = new Serial(this, Serial.list()[0], 9600);
 // don't generate a serialEvent() unless you get a newline character:
 // set inital background:
 void draw () {
 // everything happens in the serialEvent()
 void serialEvent (Serial myPort) {
 // get the ASCII string:
 String inString = myPort.readStringUntil('\n');
 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, 0, height);
 // draw the line:
 line(xPos, height, xPos, height - inByte);
 // at the edge of the screen, go back to the beginning:
 if (xPos >= width) {
 xPos = 0;
 else {
 // increment the horizontal position:
