Question

I am flex newbie , so please forgive me if i am not using the right words to ask the following question. I want to know if there is a way to draw a circle which shows a number , like for ex. Graduated Circles representing its radius to show it’s relevance. Is there a component which already do so , if not what is the best way to do this.

Here’s a quick example on how you could do it (to be continued to achieve your particular needs)

package   {     import flash.text.TextFormatAlign;       import flash.text.TextField;         import flash.display.Sprite;     import flash.text.TextFormat;         public class LabeledCircle extends Sprite      {         private var textField:TextField;          public function LabeledCircle(radius:Number, label:String = '')         {             // Prepares the textField              var textFormat:TextFormat = new TextFormat();             textFormat.align = TextFormatAlign.CENTER;              textField = new TextField();             textField.defaultTextFormat = textFormat;              addChild(textField);              // Sets the default parameters              this.radius = radius;             this.label = label;         }           public function set radius(radius:Number):void         {             // redraws the circle             graphics.clear();             graphics.beginFill(0x000000, .5);             graphics.drawCircle(0, 0, radius);              // recenters the textfield depending on the radius             textField.width = radius * 2;             textField.x = -radius;         }           public function set label(label:String):void         {             textField.text = label;         }     } }
