Histogram

Hey I would like to draw a histogram of the three RGB components. Can someone please help me?
This is the code that I started to write:
1. size(640, 360);
  
  PImage img = loadImage("sun.jpg");
  image(img, 0, 0);
  double[]r = new double[256];
  double[]g = new double[256];
  double[]b = new double[256];
  
  for(int i=0; i<256;i++){
  r[i]=0;
  g[i]=0;
  b[i]=0;
  }
  
  for(int i=0; i<img.width; i++){
  for(int j=1; j<img.height; j++){
      color c = img.get(i,j);
      r[int(red(c))]++;
      g[int(green(c))]++;
      b[int(blue(c))]++;
  }
  }
