I'm working with somethign similar to the clock example from Processing, but I would like to alter the radius of the circle created using the maths from the example, could someone show me where in this code I can change the radius of the circle? -  I have tried changing some values but i dont really understand what it starts doing once it goes wrong! Thanks!

void setup() {
 size(200, 200);
 stroke(255);
 smooth();
}
void draw() {
 background(0);
 fill(80);
 noStroke();
 // Angles for sin() and cos() start at 3 o'clock;
 // subtract HALF_PI to make them start at the top
 ellipse(100, 100, 160, 160);
 float s = map(second(), 0, 60, 0, TWO_PI) - HALF_PI;
 float m = map(minute() + norm(second(), 0, 60), 0, 60, 0, TWO_PI) - HALF_PI;
 float h = map(hour() + norm(minute(), 0, 60), 0, 24, 0, TWO_PI * 2) - HALF_PI;
 stroke(255);
 strokeWeight(1);
 line(100, 100, cos(s) * 72 + 100, sin(s) * 72 + 100);
 strokeWeight(2);
 line(100, 100, cos(m) * 60 + 100, sin(m) * 60 + 100);
 strokeWeight(4);
 line(100, 100, cos(h) * 50 + 100, sin(h) * 50 + 100);
 
 // Draw the minute ticks
 strokeWeight(2);
 for (int a = 0; a < 360; a+=6) {
   float x = 100 + ( cos(radians(a)) * 72 );
   float y = 100 + ( sin(radians(a)) * 72 );
   point(x, y);
 }
}

Wicked that's helped a lot, it wasn't that clear in the example! I've got that working but there's still another step i'm not sure about.
I am using 'times' imported from a text file instead of using the second(), minute() & hour() functions, so when the number '3' comes through from the text file my script plots it a point on the circle (in the 3 o'clock position).
I want to make innerRadius a variable so if the the number 3 comes through again the innerRadius increases a bit. I understand creating variables and simple functions, but I cant use something like:

'if(number is 3){ innerRadius++;}'

because would need 24 of these for the hour data and far too many for the minutes, any ideas of a better way I could approach it? Thanks!

Well, im making a graph that plots the hour and minute digits from a list of times onto a clock.

Part of the code I have pulling data out of the text file gives the 'hour number' as an integer, then another variable maps it to fit TWO_PI, so it sits at the correct angle on my 'clock'.

I want the plotted points to increase their inner radius every time there is a repeated number eg so if my list of time data was 10:10, 12:23, 12:01, the '12 o'clock' point would have been extended twice, making it twice as high as the '10 o'clock' point.

Maybe it would be easier to look at my code, for the data file just paste this into a text file calles testnums2.txt:
01441      pm      sym      
01551      pm      sym
02332      pm      sym
01818      pm      rep
02002      pm      sym
02020      pm      rep

and my code is:
Code:

   Table dataTable;
   int currentRow = 1;
   int level;
   int lastLevel;
   PFont textfont;




  void setup(){
   size (400, 400);
    dataTable = new Table("testnums2.txt"); 
  }



  void draw(){
   noStroke();
   fill(162, 205, 90, 10);
   ellipse(width/2, height/2, 290, 290);

   textfont = loadFont("ArialMT-12.vlw");
   textFont(textfont);
   text("click anywhere to continue", 20, 20);
  
   
   
   int time = getTime ();//gets the current time in 4 digits using getTime() function.
   float timeMapped = map(time, 0, 2400, 0, 200);// Creates a float of the current time mapped to 0, 200.
   
   int previousTime = getPreviousTime ();// gets previous time.
   float previousTimeMapped = map(previousTime, 0, 2400, 0, 200);//maps previous time to 0, 200.

     text(time, 20, 20+(currentRow*10));
   
   
   int hourNumber = getHour ();//gets hour number.
   float hourCircular = map(hourNumber, 0, 24, 0, TWO_PI * 2) - HALF_PI; //converts hour number to a map of hours into degrees
   fill(255, 0, 0);
   noStroke();
   ellipse(cos(hourCircular) * 150 + 200, sin(hourCircular) * 150 + 200, 5, 5); //ellipses at hour marks around centre 200, 200.
   
   int previousHour = getPreviousHour();
   float previousHourCircular = map(previousHour, 0, 24, 0, TWO_PI * 2) - HALF_PI;
   fill(0, 0, 0);
   ellipse(cos(previousHourCircular) * 150 + 200, sin(previousHourCircular) * 150 + 200, 5, 5);//ellipses at previous hour point.
   stroke(0);
   line(cos(previousHourCircular) * 150 + 200, sin(previousHourCircular)* 150 + 200, cos(hourCircular) *  150 + 200, sin(hourCircular)* 150 + 200);

   //println(hourNumber);

  
  
  
  
   int minuteNumber = getMinute (); //gets minute number.
   float minCircular = map(minuteNumber, 0, 60, 0, TWO_PI) - HALF_PI; //converts min number to a map of hours into degrees
   fill(255, 0, 0);
   noStroke();
   ellipse(cos(minCircular) * 50 + 200, sin(minCircular) * 50 + 200, 5, 5); //ellipses at min marks around centre 200, 200.
  
   int previousMinute = getPreviousMinute();
   float previousMinCircular = map(previousMinute, 0, 60, 0, TWO_PI) - HALF_PI;
   fill(0, 0, 0);
   ellipse(cos(previousMinCircular) * 50 + 200, sin(previousMinCircular) * 50 + 200, 5, 5);//ellipses at previous hour point.
   stroke(0);
   line(cos(previousMinCircular) * 50 + 200, sin(previousMinCircular)* 50 + 200, cos(minCircular) *  50 + 200, sin(minCircular)* 50 + 200);
   
   println(time);

I'll give that a try cheers:) L.
