绘制扇形统计图 效率和功能仍有待提高 主要是一些代码的应用！

  //绘制扇形统计图 
  import fj.graphics.*; 
  import fj.seach.JToolTip; 
  import fj.math.JDegree; 
  test = JGDI.getInstance(); 
  test.target = _root; 
  var a = [30, 30, 15, 10, 15]; 
  var b = ["第一季度", "第二季度", "第三季度", "第四季度", 
  "第五季度"]; 
  drawing(a); 
  delete a; 
  function trans(a:Array) { 
  //把数据进行转换 
  var l = a.length; 
  var t = 0; 
  for (var i = 0; i<l; i++) { 
  t += a[i]; 
  } 
  for (var i = 0; i<l; i++) { 
  a[i] = a[i]*360/t; 
  } 
  } 
  function drawing(a) { 
  //绘图函数 
  trans(a); 
  var c = []; 
  var l = a.length; 
  var t1 = 0; 
  var t2 = 0; 
  for (var i = 0; i<l; i++) {

  t1 = t2-a[i]; 
  c[i] = (t1+t2)/2; 
  var temp = this.createEmptyMovieClip("draw"+i, i); 
  test.target = temp; 
  test.fillSector(new JSolidBrush(random(0xff9900), 20), 200, 150, 150, 150, t1, 
  t2); 
  test.drawSector(new JPen(2, 0xff0000, 60), 200, 150, 150, 150, t1, t2);
