I am trying to write application that splits up user input text and creates a visualisation from it. I have allocated x,y coordinates to certain parameters that appear in words. According to the user input i am collecting these coordinates in an arraylist, then put them into an int[] and from there draw shapes at the specific positions. This works fine. I then want to link the shapes with lines. This doesn't work. Suddenly the program draws more lines than its supposed to, and seems to get 0 values from somewhere. I have put the code below. can anybody help?


void drawInCorrectPosition(String[] two, String[] twoGrams, String[] lines, color[] c1, color[] c2, float[] r, float[] g, float[] b, int[] car1, int[] car2)
 {

   ArrayList thatXPos = new ArrayList(); //new arraylist to store all the x values and then when drawing run throught these x values


   for (int i= 0; i < twoGrams.length; i++) // compare user input with preset list
   {
     for (int j = 0; j < two.length; j++)
     {
       if(twoGrams[i].equals(two[j])  == true)
       {
         int xpos = leftmargin + ( i * 3);
         thatXPos.add(new Integer(xpos)); 
         int[] xPosCount = new int[thatXPos.size()];  
         for (int k = 0 ; k < thatXPos.size(); k++)        
         {
           xPosCount[k] = ((Integer)thatXPos.get(k)).intValue();      

           int y = height - 200;                    
           noStroke();
           fill((c1[j]+c2[j])/ 2);
           rect (xpos,y, 30, 40);   //put a rectangle for every stored number in the int[]

           callLines(y, two, twoGrams, xPosCount, xpos);    
         }
       }
     }
   }
 }

 void callLines(int y, String[] two, String[] twoGrams, int[] xPosCount, int xpos)  
 {
   for (int i = 0; i < xPosCount.length-1; i++)  //connect the rectangle with u-shaped line
   {
     int lineStartX = (xPosCount[i]+30)+i*4;
     int lineEndX = xPosCount[i+1]+30;
     
     stroke(100);
     noFill();
     beginShape();
     vertex(lineStartX, y+40);
     vertex(lineStartX, y+51);

     vertex(lineEndX, y+51);
     vertex(lineEndX, y+40);
     endShape();
   }
 }
