Using an ArrayList of Point Objects may have sped up the plotting, but I am not sure.

Here is my code for displaying to the screen:

2.   //This method displays each individual point to the screen
3.   void display() 
4.   {
5.       if(path == false)
6.       {
7.         background(255);
8.         showGraph();
9.         
10.         //The plot color is also specified 
11.         stroke(plotColor); fill(plotColor);
12.         //Line thickness = 4
13.         strokeWeight(4);
14.     
15.         //The point method takes in two parameters, in this case
16.         //The xpos and the new ypos that is configured as a result of the new coordinate system
17.         point(xpos, new_ypos);
18.         
19.         //The plot color for the velocity lines
20.         stroke(orange); fill(orange);
21.       
22.         line(xpos, new_ypos, xpos + xspeed*2, new_ypos); //Draws the velocity in the x direction
23.         text("VX", xpos + xspeed*2, new_ypos); 
24.         line(xpos, new_ypos, xpos, new_ypos + yspeed*2); //Draws the velocity in the y direction
25.         text("VY", xpos, new_ypos + yspeed*2);   
26.         line(xpos, new_ypos, xpos + xspeed*2, new_ypos + yspeed*2); //Draws the total velocity
27.         text("Total Vel", xpos + xspeed*2, new_ypos + yspeed*2);
28.         
29.         //Removes all points from PointArray
30.          PointArray.clear(); 
31.       }
32.       
33.       else
34.       {     
35.           background(255);
36.           showGraph();
37.           
38.           //The plot color is also specified 
39.           stroke(plotColor); fill(plotColor);
40.           strokeWeight(4); //Line thickness = 4
41.            
42.           for(Point i: PointArray)
43.           {
44.              drawPoint(i); //Draw each Point to the screen
45.           }
46.           
47.           //The plot color for the velocity lines
48.           stroke(orange); fill(orange);
49.           
50.           line(xpos, new_ypos, xpos + xspeed*2, new_ypos); //Draws the velocity in the x direction
51.           text("VX", xpos + xspeed*2, new_ypos); 
52.           line(xpos, new_ypos, xpos, new_ypos + yspeed*2); //Draws the velocity in the y direction
53.           text("VY", xpos, new_ypos + yspeed*2);   
54.           line(xpos, new_ypos, xpos + xspeed*2, new_ypos + yspeed*2); //Draws the total velocity
55.           text("Total Vel", xpos + xspeed*2, new_ypos + yspeed*2);
56.       }
57.   }
