   document.EField.addCharge(0.25+Math.random(),0.25+Math.random(),3);


   document.EField.setChargeLabel("3"); 


   document.EField.addCharge(0.25+Math.random(),0.25+Math.random(),-1);


   document.EField.setChargeLabel("2");  


   document.EField.addCharge(0.25+Math.random(),0.25+Math.random(),1);


   document.EField.setChargeLabel("4"); 


   document.EField.addCharge(0.25+Math.random(),0.25+Math.random(),-3);
