Hello,
sending information to the canvas from the next lower level of draw(), how can I get an actualization of the canvas immediately?
I try to visualize data from the iterations of a bubble-sort. When actualizing from draw(), everything is fine, but when I try the same from inside the Bubble-routine whch is called in draw(), I only get an actualization returning to the draw()-function. What can I do?

 Here is my code:

int[] vec = {10,2, 28,29,4,19,7,88,1,0};

void setup()
{
  size(300, 300);  
  frameRate(150);                          
  noLoop();
}

void draw() {  
  fill(0,0,0);
  //paintEl(vec, 20,100);        // canvas actualization
  bubbleSort(vec);
  //paintEl(vec, 150,200);       // canvas actualization
}

void bubbleSort(int array[])                            
{
  boolean swapped = true;
  for ( int i=array.length-1; i>0 && swapped; i--)
  {
    swapped=false;
    for (int j=0; j<i; j++)
    {
      paintEl(vec, j+150,j+200);      // NO canvas actualization
      delay(100);
      if (array[j] > array[j+1]) { 
        int temp =array[j];
        array[j] = array[j+1];
        array[j+1] = temp;
        swapped=true;
      }
    }
  }
} 

void paintEl(int [] array, int startrow, int startcol) {
  ellipse( startrow, startcol, 5,5);
}

Thanks for help in advance!!
