Thread: code to draw circles on a chart

Good morning, I'm in the middle of a course project where I have to make a circle chart with a vector, spacing, color and radius as argument. But as you can see in the picture you are making squares instead of circles. Can you give me a hand?

here is the image of the result, I don't know why it's not making a perfect circle

static ColorImage circle ( int[] v, int raio, int espaçamento, Color cor){
    	  ColorImage circle1 = new ColorImage ((v.length*(2*raio))+(v.length-1)*espaçamento, max(v)+raio+1);
    	  int x= raio+1;   
 
    	    for (int i = 0; i<v.length; i++) {
    	    	 setcircle1(circle1, v[i], raio,x , cor); 
    	    	 x=x+espaçamento+(raio*2)-1;
    	     }    
 
      return circle1;
 
}              
 
 
 
 
 
 
	          static void setcircle1(ColorImage circulo, int y, int r,int x, Color cor ){
	        	 for(int i=-r;i<=r;i++)
	        		 for(int j=-r;j<=r;j++)
	        			 if( ((i*i)+(j*j))<=r*r){
	        			 circulo.setColor(x+i,circulo.getHeight()-1-(y+j),cor);
 
 
	         }
 
	          }

so that I can see the circles I use the perspective of this link: http: //pandionj.iscte-iul.pt.
It is a learning software from my college.
