Processing program using OSC messages

Thanks for your advice.I made the following changes to the program.I used accelerometer data.The arm is shaking according to accelerometer data but its not showing a fix position as the accelerometer data is also fluctuation.what changes should i make to stabilize the arm?

float p, q;
float angle1 = 0.0;
float angle2 = 0.0;
float segLength = 100;
import oscP5.*;
import netP5.*;
OscP5 osc;

void setup() {
  
  osc = new OscP5(this, 10000);
  osc.plug(this, "shake", "/accelerometer");
  
  
  size(640, 360);
  strokeWeight(30);
  stroke(255, 160);
  
  p = width * 0.3;
  q = height * 0.5;
}

void draw() {
}
void shake(float x, float y, float z){
  background(0);

  println(x+"," + y+","+ z);
  angle1 = 0;
  angle2 = (x);
  
  pushMatrix();
  segment(p, q, angle1); 
  segment(segLength, 0, angle2);
  popMatrix();
}

void segment(float p, float q, float a) {
  translate(p, q);
  rotate(a);
  line(0, 0, segLength, 0);
}
