Trying to plot coordinates around the edge of a circle
Assuming that (x0, y0) is the center of your circle, and r is the radius:
var items = 4;for(var i = 0; i < items; i++) { var x = x0 + r * Math.cos(2 * Math.PI * i / items); var y = y0 + r * Math.sin(2 * Math.PI * i / items); $("#center").append("<div class='point' style='left:"+ x +"px;top:"+ y +"px'></div>"); }
